In a normal menstrual cycle, you would ovulate around day 14, counting day one as thefirst day of your period. If you have a fairly regular cycle of about 28 days, complete thetest on day 21 and we will determine if you ovulated and produced adequate hormonesto sustain a pregnancy. If your cycle is consistent, but is shorter or longer than 28 days,estimate when you would begin your period and count backwards 7 days. That would beequivalent to a collection on day 21 of your cycle.

If you get your period irregularly, then wait until you have a period and collect your firstsample 21 days after you begin bleeding. Then if you have your period on day 28, collecton day 3. If not, collect on day 38 (10 days after your first collection).

Yes. The ranges of bloodspot hormones are essentially identical to serum, so thehormone levels should be familiar to your doctor.
