Hey everyone..I'm new here (I usually post on a different board) and I have a few questions. I started taking Yasmin this month (currently on the last pill of the 2nd week). I am getting cramps, even though I shouldn't get my period for another 8 days. I used to take Ortho Tri Cyclen and didn't get cramps until a few days before my period (even though I was in horrrrible pain for that time, lol) Did anyone else notice an initial acne breakout while switching pills? Also, how effective is Yasmin at preventing pregnancy? I read in the pamphlet that if you're a "Sunday starter" you should't have sex during the first week of pills. Is that true for just the first pack of pills, or every pack? Thanks, I appreciate any feedback
