Abnormal Pap smear

Has anyone ever had an abnormal Pap during pregnancy? I have been followed for a couple years now for LSIL and have had two colposcopies. I am 12 weeks pregnant and has a pap come back with HSIL (high grade dysplasia). I have a colposcopy on Monday. I am just so scared that I am either going to have to loose the baby or get cervical cancer. Anyone with a similar situation in the past ?
