Well, actually you are both wrong.
Hpv is sexually transmitted .B.O.T.H the high risk kind and the kind that causes warts (low risk).
Your body can clear hpv on it's own. It is unknown how this happens, but your body can get rid of it. There is no 'cure' for it though.
You shouldn't have to do anything if you have hpv other than continue getting pap smears. There is no risk to your pregnancy.
Nothing is done for 'just' hpv. You will continue to have pap smears as scheduled to see if it is causing any changes on your cervix and if that does happen, you will have a colposcopy and possibly a biopsy (a very small bit of cervix is removed for testing) to see what kinds of cell changes are going on. After that you may need a leep to have those surface cells removed. None of this is that terrible.
You should know that approximately 80% of sexually active women will get hpv in her lifetime. It is not uncommon and it isn't life threatening.
Good luck and congrats on your pregnancy!
