I been taking BC since was 15 then i stopped having sex for about 9 months, so i stopped taking the pill! I started taking Aviane 16 days ago. Gosh the first day I took the pill, I felt so sick i couldn't eat anything I just wanted to vomit. This continued for like the whole week. I then became so irritated, like everything just got me super angry. I was yelling so much at everyone for very stupid reasons. The thing that freaked me out the most was i bleed for like two weeks (I wasn't sure if i had a miscarriage) I still have bad cramps! and still have super bad mood swings. From reading all of these comments it seems like my body just isn't use to all the hormones, a lot of people mentioned that waiting for 3 months is the right thing to do. Everyone's body is different, I'm emotional as it is when it comes to my period. So will see what happens! I mean it sucks to go threw these symptoms especially when your only 17 and not sexually active! Oh yeah I want to add one more thing, i haven't experienced any weight gain. I'm already tiny (108 pds) so I actually wouldn't mind gaining like 10-15 pds! and my breast's haven't gotten bigger =( there's no swelling. So I think I'm fine. I just want the moodiness to go away! hope I helped!
