Thanks for the reply. I had an ultrasound appointment once but I was too scared to go, even though i know it's non invasive. I should do that, you're right. It just seems to be hormone related because I generally bleed at the same time every month, about a week before I should and it all started when the low dose pill craze started, yet I'm scared to go back on a higher dose pill because I don't want my acne to get worse. Nasty little problem I've developed for myself. My gyn recommended demulen. Has any one tried that, she said it has a very low incidence of breakthrough bleeding, but what will it do to my skin? I'm afraid to go off the diane because everyone thinks its such a miracle (especially my derm) and when I talk to her about trying something different she makes a funny face and makes comments like "do you really want to risk losing control?"(of my acne). Though I don't really feel that 'in control' anyway. But as I'm sure many of you have experienced, my skin is always on its best behaviour when my derm appointment comes around.
