Re: I'm kind of worried....
You should be okay to wait until your colposcopy appointment, if it's just next week. But to put your mind at ease, it wouldn't hurt to give your doctor a call, just to make him or her aware of what is going on.
From what you describe with the irregular periods, that seems to be a hormonal problem. How old are you, if you don't mind my asking. I know that when I was in my late 30's, my periods were really irregular, in part from peri-menopause, and in part from uterine fibroids.
As for the bleeding after sex, that might be a concern, particularly with the abnormal Pap tests. It's good you're having a colpo next week, just to be on the safe side.
I hope everything turns out okay. Let us know what you find out.
