I went on this POISON Yasmin for a year then went off after I gained weight. I proceeded to lose so much weight after I went off that I lost 40 pounds by doing nothing different over the course of three months. I got so skinny people became concerned but there wasn't anything medically wrong with me. However, I also didn't have my period for over a year after quitting Yasmin. I went to the gyno concerned but after a Progesterone test (which I failed) he suggested I just try going back on again with Yaz this time. I had my periods again of course but not on my own. They were hormonally controlled. After two months, I started craving food and getting anxious and stuffing my face as a way to cope with the mood swings and stress. This is was so not like me. Then I started to get horrible bloating and constipation. I had to use laxatives regularly to have any movement. After gaining 30 pounds and suffering in severe with the constipation, I decided it had to be the pill so I went off again. No surprise, I haven't had a period for 6 months since I've been off and while the crazy mood swings have gone away, I'm still having really bad GI problems. I have a sharp pain in my lower left bowel and I'm chronically constipated. After seeing doctors and running blood test which all ended up normal they still don't know what's wrong even though I tell them it's because of this pill. My gyno thinks I'm crazy, my GP thinks I'm crazy, and now I have a GI who thinks I'm crazy. IT'S BECAUSE OF YASMIN/YAZ!! This is POISON. Do NOT take this or give it to you kids. I'm just praying I can heal the pain and the constipation soon because I'm starting to limp and all the doctors have told me to do is eat a different diet. I've been eating cooked fruits and veggies for almost a month now because that's the only thing I can eat without severe pain. And I'm a 24 year old healthy girl who exercises every day. I am beyond amazed this crippling drug is still on the market place.
