My girl is really getting worried and I am a little too now. She was on one pill for about 6 months and had a lot of bleeding all the time so they switched her pill. She has been about 3 months and hasnt had a period on it. She told her doctor and they said it could take a while for her body to get used to it and resume normal cycle. She had a pregnancy test at the doctors and it was negative. She has been very good about taking her pill and hasn't missed a day. We always use condoms as a second form of protection so to me, I don't think we have anything to worry about. We have always used them correctly and never had a break. Is it normal to go this long on a new pill? What should she expect in the future.
