Hpv!!

So I got a call to do a biopsy for my abnormal pap I just found out that I'm pregnant is it OK to do the biopsy will it cause a miscarriage? Will I be OK I'm scared and don't wanna go through another miscarriage. I'm just terrified my husband says I should wait till after pregnancy to do a biopsy! Should I? My obg told me it wasnt to be concerned that it'd go away on its own they just want to test my tissues to see what it is! Please anyone who's gone through this or know someone who has been through this!!!!
