Sometimes you just have a few abnormal cells, I was told that pregnancy and hormones can do it, but there are so many things that it could be. It's good that all looked well, I had an abnormal pap about 2 years ago, but mine didn't go as well and I had to have cryo treatment to remove the cells. Most of the time though in a case where it's mild the cells will go away on their own, they just have you come back as a precaution, I had to go in every few months for awhile then 6 months, now I'm back to yearly. Call your Dr. if you have questions though, hope it stays good for you.
