I have taken YAZ for over a year now and have recently stopped after running out. I have recently started gaining weight, becoming moody, but I have noticed that I have a lot more energy where as before I was sluggish and had a very hard time getting out of bed. I would get up late and take a nap in the afternoon. It got bad enough that I was running late to work, and was not able to get up to attend class on time. Lately I have been up early and have stayed up all day. I wish the weight gain would go away being that I've gained about 20lbs in 3 months and I feel hungry all the time. My big problem is that my period has been about a day in length or non-existent (I know lucky me) but I have never had this problem. My period has been regular since it started 12 years ago. I take pregnancy tests every month being that it makes me nervous that I could be pregnant and they come out negative. The doctor doesn't seem concerned and says it'll start again. Im curious if anyone else has experienced this problem in stopping bc because this is the first time I have ever stopped taking pills. It makes me nervous as to whether I should be seeking different health care being that I am still young and have not had children yet.
