Patient: In March of this year I had a d&c and exploratory hysteroscopy because I was having 2 periods a month. Since then, I’m having periods that last 10 to 12 days. My current medications are metformin which I started in April and Parlodel which I started in March for elevated prolactin levels. The parlodel dropped them significantly. My question is why is this happening? I called my ob/gyn yesterday morning and was told he would call me back, but hasn’t yet. Help?
