I've been on Yasmin for about three months now because I used to miss my periods, freaking out thinking I was prego which would be hell because I am only 19! My doctor recommended it to me. I was on it for about one week a long time ago and stopped because it didn't get rid of my acne and when I went back to her she said it would definitely be at least two months until it cleared up. Finally my acne is clearing and my periods are regular, I used to go two to three months without a period. So far everything has been great except horrible head aches and most importantly, MOOD SWINGS!! Wow. I just moved in with my boyfriend about a month ago and I snap him 247 for no reason> I pick fights like a drunken bar fly and I have been having spurts of crying almost every day and thoughts of suicide. I don't know what to do and I am unsure if it's just me or the BC? After reading all these horror stories I don't know if it's hurting me or helping me! I am afraid if I go off of it that my skin will break out like it used to and I don't want to confuse my body cause it's just starting to become used to it. What should I do? Right now I can't afford to go to the doctor again it was $200 just to sit with a new gyno for literally 3 minutes! I only work part time and I just want advice, because I don't have health insurance and it's not fun being me right now!! Please, any suggestions?
