Post partum

I have had around 4 years of mild dyskariosis results and positive HPV which means I have had annual colposcopies (none of which required biopsy). I missed my colposcopy last year due to being pregnant. I gave birth vaginally in October and then went to hospital for a smear in January. The results showed normal cells bit still HPVpositive. I'm just wondering if birth can naturally clear abnormal cells? And also is there anything I could do to try clear the HPV as it really concerns me that it's been there a long time now. I'm due another colposcopy in October.
