When taking birth control pills, what tests are helpful?

Saliva testing for DHEA-S and cortisol as well as blood spot testing for thyroid, Vitamin D, and CardioMetabolic markers is definitely beneficial for women taking oral birth control pills. Collect your sample on day 20 of your cycle, counting your first day of bleeding as day 1.

Please note, if you and your medical professional decide to discontinue your oral contraceptives, you should wait until your next menstrual period to collect. It may take approximately 7 weeks before you are able to collect your sample after discontinuing the pill as failure to ovulate is common in many women immediately after discontinuing birth control pills.
