I have been on yasmin for a bout a year and a half and I love it!!!!!! Well here is what I experienced. The very first month I experience break outs too, but after that first pack, I had wonderfully clear skin, i've never had an acne problem but I think that on yasmin my face is clearer than before taking the pill, but like I said the first month I did break out. Now I only get pimples when my period is on or coming on like normal, but besides that I have clear skin.
About not getting your period yet, I remember that on my first pack of yasmin I didn't get my period until the friday of the placebo pills, and I am a sunday starter, I too was worried but it came. After that I started to gradually get it earlier in the sugar pills week, now I am steady on getting it the wednesday of that week, it never fails.
As far as any other symptoms, at first I experience a little bit of morning sickness because I take it at night, but that too went away. Honestly I have not experience weight gain, lost of sex drive, or anything like i've heard some other people have experienced...... I wouldn't trade yasmin for the world! The only thing I have had is spotting if I take two pills late, this has only happened once and it was really annoying because I spotted for three weeks!!!!! But I can't complain that was my fault, so beware do not take your pills late!!!!
I can't say that your experience will be as pleasant as mine since everyone's body is different, but only good things to say about yasmin here!!!!!!
