My doctor just prescribed this pill to me since my migraines have gotten more frequent& severe over last year, so no more estrogen. After reading all the reviews & the doctor warnings- I'm VERY nervous. Does everybody that takes this pill own stock in pregnancy tests? I feel like I'm going to be buying every month out of fear. Does anybody only get one NORMAL period a month? I get suffering from break through bleeding 1-3 months but having month long periods is f'd up! Very nervous to start this weekend..
