I started Yaz November 2007 since my periods were heavy and I had really bad cramps. I am a medical student and I was starting my surgery rotation so I thought I couldn't deal with the cramps during surgery, so that is why I started. It seemed great at first I had no appetite, my weight has been stable. I read a lot of different books saying hormones shouldn't be taken since it isn't natural and it will cause weight gain etc. One thing for sure is that the distribution of my fat has changed, now I have more belly weight (like the other person who mentioned the yaz roll), more weight in my arms and a little more in my breasts and less in my legs. I have been contemplating for a long time if I should stop taking it also because I am someone with A LOT of scalp hair and I noticed that I lost A LOT of it while on Yaz (but could it also be from the stress of medical school?). My life has been crazy, my father died in September. I cant differentiate if I am crazy/sad/moody bc of my life circumstances or bc of the pill because sometimes I do feel like I am over reacting. I wonder too if I stop the pill if my fat will redistribute again. I am so unsure what to do. I have also noticed that I cannot wear contacts for a long time, sometimes I get debilitating headaches where I cant even lift my head.
