The same canвЂ™t be said, though, for all fertility hormones. This means you can measure it on any day of the month and expect a similar result. In the menstrual cycle, some hormones are pretty steady throughout, but others experience high highs and low lows.ДЄnti-Mullerian hormone (AMH), for example - which is the best hormone for measuring ovarian reserve, or your egg count - has a constant presence throughout the entire cycle. Like in any good drama, individual hormones have their own character arcs and moments to shine. You can read the Modern guide to the menstrual cycle for more details. And, of course, as soon as the curtains close on your menstrual cycle, another performance starts up again and repeats throughout your reproductive years (until menopause). In each of these вЂњacts,вЂќ certain hormones play a leading role in moving the events of the menstrual cycle forward. If an egg isnвЂ™t fertilized, then you get your period (and begin the follicular phase all over again). Act 3: The luteal phase, or when your body is ready to support implantation and pregnancy if an egg is fertilized.Act 2: Ovulation, or when one ovary releases the most developed egg and it travels through the fallopian tube to meet up with sperm for fertilization.Act 1: The follicular phase, which includes the days youвЂ™re on your period, the maturation of ~15-20 ovarian follicles (tiny sacs that house and release eggs) and the thickening of the uterine lining.Basically, you can think of your menstrual cycle as a play with three acts: So what makes day 3 the magic day for fertility hormone testing? To answer this question, letвЂ™s zoom out for a quick refresher on the menstrual cycle. Whether you get a period or not and what birth control you're on will dictate if testing day 3 hormones is an option for you right now.ДЇirst, a refresher on the menstrual cycle.

If you have a super-short period (lasting fewer than 3 days), testing on day 2 is the way to go. Days 2-4 are okay for testing as long as you're still experiencing flow.Cycle day 3 is when many reproductive hormones are at the level doctors consider 'baseline.'.WhatвЂ™s so special about cycle day 3, anyway? In this post, weвЂ™ll break down why some hormones are day 3-dependent, how you can find your day 3, and what your options are for testing if you donвЂ™t have a period. If you are on birth control, the hormones youвЂ™ll test for (and the day youвЂ™ll need to take your test) depend on the type of birth control youвЂ™re on and whether or not you get a regular period.If youвЂ™re not on hormonal birth control and you get a regular period, your Modern Fertility Hormone Test will measure what are called day 3-dependent hormones, and your testing instructions will specify that you take your sample the third day of your period.(In fact, weвЂ™ve conducted a peer-reviewed clinical study showing that the results from our home test kit are as accurate as what youвЂ™d get from a traditional lab draw.) With the Modern Fertility Hormone Test, we follow the same standards of fertility hormone testing that they do in a fertility clinic. Depending on how long youвЂ™ve spent getting to know the ins and outs of the fertility world, you might have heard about the concept of вЂњday 3 testing.вЂќ In a nutshell, day 3 testing (also called вЂњcycle day 3вЂќ or вЂњCD3вЂќ testing) refers to the clinical standard of measuring fertility hormones via a blood test on the third day of your period.
