I've been taking Yaz for about a year and a half. I also take lexapro to help even out extreme mood swings I would get (2 weeks before my period). For a while, probably the first year, I just felt more tired, which I thought was because of the lexapro. In the past 6 months though, I have been getting a stomach flu type illness every month, 3 days after I start my new pack of pills. I also have a very sensitive stomach and get sick easily. I recently lost 5 pounds (from 125 to 120) without making any lifestyle changes. Also, this year I've had low iron levels, and noticed my stools are black from time to time. I went to the doctor today to have my blood checked and also submitted stool samples. Could this all be from Yaz? I have been getting the flu (or flu like illness) way too much this year, and my boyfriend never catches it from me. I am worried about going off the medication because the yaz and lexapro have really controlled my mood swings, and my skin gets much worse without birth control. I'm just worried something more serious is going on here. I am 26 and a healthy eater, so I don't understand all the stomach problems! Does anyone else have these issues? Especially after starting a pack of pills (I feel fine the week of my period)...
