Yaz Birth Control Help

I used to use birth control - unfortunately now I ain't getting any and know that I shouln't really use it with being a smoker anad serious circulation problems. When I was on it though I found absolutely no side effects at all and everything was great. I was on one brand here in the UK but when I moved to Canada I went to the doctors and they didn't have the same brand. But it was a Welsh doctor who prescribed something to me and told me that the active ingredients in it were the exact same so it was effectively the same pill. Although I had no problems I went to a friend that went to the same doctor, got prescribed the same thing and she basically said she ended up feeling like she had PMT all the time. I have never heard this from anyone else and she said that when she did have her period it lasted even longer which was strange. She didn't even bothering changing brands though, as that was the first time she tried it she just came right off them and hasn't went near them since. She said she couldn't even handle another week of feeling like that. I hope that everything works out for you.
