I took Yaz a few years ago for six days. I began taking it to help with PMS symptoms, which in hindsight was silly because I would start at 7am on the 17th of each month and be done by 7am on the 18th. But my cramps were so bad that I couldn't do anything but sit on the bathroom floor sick as can be. So I tried it. And... now my cycle is all screwed to hell still. Like I said, it's been about three years now and I thought things would have gotten at least regular by now, but now I have the debilitating cramps for a week or longer instead of 24 hours. I've been toying with the idea of doing an aas cycle, but now after reading one of supergirl's posts, I don't think I will try it, especially after my experience with Yaz. Anyone else had an experience like this with birth control and how long, or what did they do, to regulate things a little better? I'd rather stay away from trying another one, but I'm not sure if where things are now might effect my husband and I from having kids. (I stopped the Yaz after six days because I got an eight hour long nose bleed which ended in me passing out at work and being rushed to the hospital. My doctor at the time had told me to keep taking it and that this was a normal side effect. Yeah, right.)
