I started Yas about 4 months ago for excessive bleeding, cramping, pms symptoms and homonal imbalance. My Gyn said it would help with all these things. On my first couple months on the pill I thought it improved my mood swings, and my bleeding drastically decreased and I had almost no cramping. I did have a couple migraines and some nausea in the beginning. I have had a real problem with weight gain, cravings and bloating. I increased my exercise but can not seem to loose the weight I gained when I started Yas. I am 40 and this was never a problem for me before. For about the last six weeks, I have had depression and extreme irritability. I've also had brown spotting in between periods. I'm going to stop taking the Yas.
