i have been taking bc for around ten years and this is my first time with seasonique. I have been taking it just as prescribed but the last three weeks of the blue pill i did not use a back up method control method. I am in a long term relationship and I thought i would be protected. However i am beginning to worry because i just took my second to last yellow pill and i have still had no period. I took two pregnancy tests (three days after i was late) two days apart (and five days after i was late) and both are negitive. I am am in super anxiety mode!!! i thouight i did everything right????

Birth Control Answer A7003

Most birth control pills contain hormones that are supposed to be taken for 21 days, and then stopped for the next seven days or optionally, pills with another color that do not contain the hormones. During this period the menstrual period should start due to the sudden change of the female hormone levels induced by the sudden stop of hormonal intake. On what day the period would start and how long it would last might be different in every woman.

However, missing the period completely or having it last for more than only a few days might be a good reason to schedule a visit to your gynecologist.

According to the data you provided (late start of menstrual period, and two negative home pregnancy tests), it cannot be determined for sure whether you are pregnant or not. You probably understand that to confirm or to rule out pregnancy, a physical examination, hormonal laboratory tests, and an ultrasound scan might be needed at the gynecologist office. However, do not overreact on this issue, because the condition you experience might also be due to a hormonal imbalance or just a normal variation of the menstrual period length. It might be best to let the gynecologist check what the exact reason is.
