Goldberg how long does medication stay in your system?Dear, Dr. Goldberg, thank you. So if I take a drug test, I would come clean in 5 days? I'm taking the medication because I am bodybuilding and it helps me sleep for 14 hours. I gain around 10 pounds in a week for the the first month.
The test is usually given on day 3 of your menstrual cycle, though most doctors are OK with the test being done on any day between days 2 to 4 of your cycle. (The first day of your cycle is the day your period begins.) FSH levels may also be checked at another time during the menstrual cycle, but this is uncommon.
Ideally, you want 12 or more days. But if your luteal phase is fewer than 10 days, you may have low progesterone. How do you test your progesterone level? Progesterone spikes after ovulation and continues to rise for several days. Progesterone should be tested when progesterone is highest, in the middle of the luteal phase. Typically, doctors ask women to come in for a test on day 21 of their cycles, because in the average 28 day cycle, day 21 falls in the middle of the luteal phase.
