36 Weeks Pap Smear Abnormal

Got a pap smear done at 36 weeks and Dr. said they found abnormal cells low grade squamous intraepitelial lesion which is caused by HPV. He said not to worry because pap smears at this point in pregnancy are inaccurate and since I had already dilated when I got the pap smear done that could have definitely affected the results. Has anyone gone through this?
