Abnormal Pap smear but only been one with one fiy

Is there a reason why I would have abnormal cells if I’ve been committed to one guy my whole life? I know he has a pass but I’m really questioning something. We are married with two children. She says they are abnormal but same as my last abnormal pap so she doesn’t want to do a colposcopy but go right to 6 month paps.

She also thinks a miscarriage triggered this. Has this happened before to anyone?
