To that end, you might be using an ovulation tracker to find your fertile window. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">There are a variety of tools (apps, <a href=\"https:\/\/www.avawomen.com\/avaworld\/fertility-calendar\/\">fertility calendars<\/a>, <a href=\"https:\/\/www.avawomen.com\/avaworld\/ovulation-calculator\/\">ovulation calculators<\/a>, and <a href=\"https:\/\/www.avawomen.com\/avaworld\/when-to-take-ovulation-test\/\">ovulation tests<\/a>) that promise to pinpoint ovulation, and therefore your fertile window. However, the reality is that the timing of ovulation is unpredictable\u2014even if you have a regular cycle.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Studies show that most women <\/span><i><span style=\"font-weight: 400;\">don\u2019t<\/span><\/i><span style=\"font-weight: 400;\"> ovulate on the fourteenth day of their cycle, as they are commonly told. (In fact, one study showed that\u00a0<\/span><a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC27529\/\"><span style=\"font-weight: 400;\">70% of women<\/span><\/a><span style=\"font-weight: 400;\"> have fertile windows that don&#8217;t fall entirely within cycle days 10 &#8211; 17.) <\/span><\/p>\n<p><span style=\"font-weight: 400;\">So, if your ovulation tracker follows the &#8220;ovulation occurs on cycle day 14&#8221; formula, then chances are it&#8217;s not accurate. Here, we\u2019ll review:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">When ovulation happens<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">How to find your fertile window<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">The best time to get pregnant\u2014backed by research<\/span><\/li>\n<\/ul>\n<h2><span style=\"font-weight: 400;\">Why it&#8217;s important to know your fertile window when TTC<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Each menstrual cycle, you have a<\/span> <span style=\"font-weight: 400;\">six-day fertile window<\/span><span style=\"font-weight: 400;\">: the five days before ovulation, and ovulation day itself. A study published <\/span><span style=\"font-weight: 400;\">in <\/span><a href=\"https:\/\/www.nejm.org\/doi\/full\/10.1056\/NEJM199512073332301\"><i><span style=\"font-weight: 400;\">The New England Journal of Medicine<\/span><\/i><\/a><i> <\/i><span style=\"font-weight: 400;\">\u00a0showed that nearly all pregnancies occurred within a six-day period which ends on the day of ovulation. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">When you\u2019re trying to get pregnant, it\u2019s important to know when you ovulate, yes. But for the best chance of conception, you really want to narrow in on those days <\/span><i><span style=\"font-weight: 400;\">before<\/span><\/i><span style=\"font-weight: 400;\"> ovulation. These are your most fertile days\u2014and the days that you want to be having sex. <\/span><\/p>\n<h2><span style=\"font-weight: 400;\">When do you ovulate? <\/span><\/h2>\n<p><span style=\"font-weight: 400;\">The short answer is: it&#8217;s variable. (Which is why most ovulation trackers won&#8217;t work.) Ovulation is a complex hormonal process driven by four different hormones: Follicle stimulating hormone (FSH), Luteinizing hormone (LH), estradiol, and progesterone. The critical thing to figure out is when ovulation happens for <\/span><i><span style=\"font-weight: 400;\">you<\/span><\/i><span style=\"font-weight: 400;\"> since it doesn&#8217;t occur according to a schedule and can even change from cycle to cycle. <\/span><\/p>\n<p>First, let\u2019s review the\u00a0<a href=\"https:\/\/www.avawomen.com\/avaworld\/the-ovulation-process\/\">ovulation process<\/a>\u00a0itself. Follicle stimulating hormone (FSH) will trigger the growth of multiple follicles inside your ovary. Relatively early in your cycle, one of these follicles will become dominant and the others will die out. That dominant follicle produces increasing levels of estrogen, which causes your cervical mucus to change consistency and pH balance and your uterine lining to thicken and grow. Estrogen then continues to rise\u2014and once it\u2019s high enough\u2014 it triggers the release of LH, which sends the signal for ovulation to occur.<\/p>\n<p>The follicle will rupture and a mature egg is released\u2014this is ovulation!<\/p>\n<p>What you\u2019ve likely heard is that ovulation occurs 14 days after your period starts. This is a myth that even some healthcare professionals still believe. But recent\u00a0<a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC27529\/\">research<\/a>\u00a0has shown that only 10% of women actually ovulate on day 14 of their cycle, which certainly isn\u2019t anything close to the majority. Most important takeaway: ovulation follows a series of hormonal events that happen each month, but the pace at which it unfolds can vary.<\/p>\n<h2><span style=\"font-weight: 400;\">Why you might be missing your most fertile days<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">There is a wide range of products promising to help you identify your fertile window. But it\u2019s important to note that not all of these tools are created equal. In fact, <\/span><a href=\"https:\/\/jabfm.org\/content\/29\/4\/508.full\"><span style=\"font-weight: 400;\">this study<\/span><\/a><span style=\"font-weight: 400;\"> found that the large majority of fertility apps are not based on evidence-based FABMs (fertility awareness-based methods). <\/span><\/p>\n<p><span style=\"font-weight: 400;\">Some fertility trackers use your average cycle length and an estimated timeframe for ovulation to pinpoint when your fertile window might be. But your peak fertility only lasts for about three days. So using averages and estimations\u2014even if they\u2019re only off by a few days\u2014may cause you to miss your most fertile days completely.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Which days are those, exactly? According to three different studies (each with slightly different findings detailed in our <\/span><a href=\"https:\/\/www.avawomen.com\/avaworld\/fertility-calendar\/\"><span style=\"font-weight: 400;\">fertility calendar<\/span><\/a><span style=\"font-weight: 400;\">), here are your most fertile days, ranked in order:<\/span><\/p>\n<table style=\"border-collapse: collapse; width: 100%; height: 48px;\" border=\"1\">\n<tbody>\n<tr style=\"height: 24px;\">\n<td style=\"width: 50%; height: 24px; text-align: center;\"><span style=\"font-weight: 400; font-size: 12pt;\">2 \u2013 3 days before ovulation<\/span><\/td>\n<td style=\"width: 50%; height: 24px; text-align: center;\"><span style=\"font-size: 12pt;\">\u00a0<span style=\"font-weight: 400;\">20 \u2013 30 percent chance of conception<\/span><\/span><\/td>\n<\/tr>\n<tr style=\"height: 24px;\">\n<td style=\"width: 50%; height: 24px; text-align: center;\"><span style=\"font-weight: 400; font-size: 12pt;\">4 days before ovulation<br \/>\n<\/span><\/td>\n<td style=\"width: 50%; height: 24px; text-align: center;\"><span style=\"font-weight: 400; font-size: 12pt;\">10 \u2013 12 percent chance of conception<\/span><\/td>\n<\/tr>\n<tr>\n<td style=\"width: 50%; text-align: center;\"><span style=\"font-weight: 400; font-size: 12pt;\">ovulation day<br \/>\n<\/span><\/td>\n<td style=\"width: 50%; text-align: center;\"><span style=\"font-weight: 400; font-size: 12pt;\">10 \u2013 12 percent chance of conception<\/span><\/td>\n<\/tr>\n<tr>\n<td style=\"width: 50%; text-align: center;\"><span style=\"font-weight: 400; font-size: 12pt;\">5 \u2013 6 days before ovulation<br \/>\n<\/span><\/td>\n<td style=\"width: 50%; text-align: center;\"><span style=\"font-weight: 400; font-size: 12pt;\">0 \u2013 5 percent chance of conception<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>The most important thing to note here is that you can conceive anytime during the 5 days before ovulation and on ovulation day itself. Within your 6-day fertile window, the 2-3 days before ovulation are your most fertile.<\/p>\n<h2><span style=\"font-weight: 400;\">Can you get pregnant on ovulation day?<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Yes, but your chances are better in the days leading up to ovulation. As the table above shows, there are varying chances of conception on each day, but conception can happen anytime in the fertile window.\u00a0 The good news is that s<\/span><span style=\"font-weight: 400;\">perm can live inside the female reproductive tract for up to five days. According to <\/span><a href=\"https:\/\/academic.oup.com\/humupd\/article\/12\/1\/23\/607817\"><span style=\"font-weight: 400;\">this study<\/span><\/a><span style=\"font-weight: 400;\">, millions of sperm are deposited into the vagina during sex, but only a few thousand of them will reach the Fallopian tubes. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">These remaining sperm will wait for ovulation to occur and once it does, will fight their way to the just-released egg. Just how the sperm knows that ovulation is happening and it\u2019s time to get going is still a bit of a mystery. <\/span><\/p>\n<p><a href=\"https:\/\/science.sciencemag.org\/content\/299\/5615\/2054\"><span style=\"font-weight: 400;\">One study<\/span><\/a><span style=\"font-weight: 400;\"> showed that sperm may be drawn to the egg through a process akin to &#8220;smelling,&#8221; but more research is needed to figure out exactly how this fascinating process works. But the point is: somehow when the egg is released, the sperm know they have an important job to do.<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">What <\/span><i><span style=\"font-weight: 400;\">are<\/span><\/i><span style=\"font-weight: 400;\"> the best options for tracking ovulation?<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">The good news is, there are a number of reliable ways to narrow in on your fertile window. Here are some options for tracking fertile days:<\/span><\/p>\n<ul>\n<li><b>Cervical mucus<\/b><span style=\"font-weight: 400;\">\u2014A few days prior to ovulation, your cervical mucus will begin to become slippery, resembling egg whites. This is a<\/span><a href=\"https:\/\/www.avawomen.com\/avaworld\/ovulation-symptoms\/\"> <span style=\"font-weight: 400;\">symptom of ovulation<\/span><\/a><span style=\"font-weight: 400;\"> and a sign that you are fertile. When you see discharge looking like this, take it as a sign that you\u2019re in your fertile window.<\/span><\/li>\n<li><b>Ovulation tests<\/b><span style=\"font-weight: 400;\">\u2014An<a href=\"https:\/\/www.avawomen.com\/avaworld\/when-to-take-ovulation-test\/\">\u00a0ovulation test<\/a>\u00a0(also called an OPK for \u201covulation predictor kit\u201d) detects the concentration and presence of luteinizing hormone (LH) in your urine. Around 12-36 hours prior to ovulation, there\u2019s a surge in LH levels. This surge can last anywhere from a couple of hours to a couple of days. The length of the surge isn\u2019t important in determining when ovulation happens, as most women tend to ovulate about 24 hours after the surge begins. Unfortunately, LH tests can\u2019t tell you if your surge just began or if it\u2019s nearing the end. The problem for TTC? By the time you get a positive LH test, there may not be much (or any) time left before ovulation\u2014and you may have missed some of your most fertile days already, depending on the timing of your LH surge.<\/span><\/li>\n<li><b>Basal body temperature<\/b><span style=\"font-weight: 400;\">\u2014Tracking your<\/span><a href=\"https:\/\/www.avawomen.com\/avaworld\/problems-with-bbt-ovulation\/\"><span style=\"font-weight: 400;\"> basal body temperature<\/span><\/a><span style=\"font-weight: 400;\"> (or BBT) is another option. With this method, you take your temperature at the same time each morning\u2014before you get out of bed or move around at all. You also need to use a special thermometer specifically designed to measure basal body temperature. The problem with the BBT method is that your basal body temperature rises <em>after<\/em> ovulation. So once you detect that temperature increase, your fertile window for that cycle has already closed.\u00a0<\/span><\/li>\n<li><strong><a href=\"https:\/\/www.avawomen.com\/\">Ava<\/a><\/strong><span style=\"font-weight: 400;\">\u2014This wearable device is clinically proven to detect the very beginning of the fertile window\u2014in real time, as it happens. You wear the bracelet each night while you sleep. \u00a0Ava\u2019s proprietary algorithm uses machine learning and artificial intelligence, combining knowledge of your cycle with the physiological data collected (parameters like resting pulse rate, breathing rate and skin temperature, to name a few) to predict your fertile window accurately.<\/span><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Once you&#8217;ve decided you want to conceive, you probably want it to happen quickly.
