I felt the need to add these postings with my experience. I'm 23 and have only been on Yasmin for two months (i just took my last yellow pill yesterday). The first month I was fine, my acne has gotten better the cramps lessened (no longer debilitating like they were) and my period got lighter. The second month everything changed. I have been severly nauseas and vomiting for going on two weeks now. Because of the nausea I haven't been able to eat very much and have lost 10lbs in less than 2 weeks, which sounds good but when you are only 100lbs loosing anymore weight is a little dangerous. I can't stand to be nauseas. Vomiting is my only fear in the world and up until recently I hadn't vomiting in 15years (i liked it that way). I have also had a very difficult time breathing. I'm very weak probably because I can't eat anything and something as simple as brushing my hair wears me out completely and leaves me panting. I'm a normally depressed person and am taking wellbutrin for it so I can't say it has made me any more depressed than usual. I also get dizzy very often so again this doesn't seem to make it any worse. I have had lots of cramps, stomach and otherwise as well as lower back pain. I don't know if that is just my upcoming period or the BC. I feel like i'm pregnant although I have taken tests saying i'm not. I hate this...I'm glad i'm not working right now otherwise i would have had to taken off these past two weeks. However I just got a job and can not continue to feel like this. I am afraid to leave my house for fear of vomiting in some remote place therefore I haven't really gone anywhere in the last two weeks. I'm not sure if these are just side effects of the pill or if it is hyerkalemia but either way I can't live like this. I wish I could continue and see if my symptoms subside but yeah I can't take the risk they won't with my new job and everything. More power to anyone who is taking it without severe side effects, i just wish i was one of you. This has been my first attempt at a BCP and i'm not sure what to do from this point on...I can't deal with side effects this severe again. If anyone has any suggestions on what pill might but best please let me know....
