Abnormal Pap smear

I went to my ob appointment yesterday to see the cause of my abnormal Pap smear my doctor had to re do my Pap smear and told me that I have a tiny bit of dyslaria it made me cry and I was so upset thinking that I might get cancer but he told me there was nothing to worry about because it's tiny and he didn't have to do a biopsy Because it was tiny he said he would check my Pap smear again 6 weeks after I give birth. Has this happened to any of you ? I read sometimes it goes away on its own?
