I had a similar thing that started with a very light spotting after sex, and then had a big irregular bleed in the middle of my cycle. I had already had a pap test that had showed very mild irregualr cells, then I had to wait 12 months to have another which came back all clear. My doctor decided to send me to the gyno just as a added precaution, for a colposcopy (I think that is what it is called) - basically a more extensive pap smear, which also showed mild irregular cells. I had to wait another 6 months which is almost up to have another colposcopy. If it shows irregualr cells again, then my gyno will laser them off.

I am a absolute stress head, so all this time between testing does freak me out. My doctor and gyno are all pretty calm about it, as I have always had regular smears. I also bleed at every pap test, but my doctor puts that down to most likely a very sensitive cervix. I couldn't dtd when pregnant at all because of the amount it would make me bleed. Since going through this, I have spoken to quite a few girls who have had the same results, and have had the laser, including my sister in law. She goes and gets pap tests every 12 months now just to be on the safe side, even though the doctor has given her the all clear and said its ok to get them every 2 years again.

Good luck chick - try not to freak yourself out googling stuff like I did
