My period has been missing for about two weeks now, and I'm not sure if it's just the chance that the new birth control I'm on is the reason or if I really am. I've taken five at home tests, only one was iffy, the other four were negative. I know that being on a new medication can mess up the tests though. I get nauseated, have to pee all the time, am always craving, but I don't have bloating, cramps or darkening of the nipples. I have testing coming in June, when I go get birth control again, but I don't know if I should go to the doctor sooner or just assume there's a chance I am and just stay healthy until I go in?
