Sorry tmi pimples/bumps outside the...

I'm not sexually active haven't had any since two months ago(as in I don't have sex often) and found out I'm pregnant. Me and my baby father haven't spoke since December. But this morning I found that I have pimples/bumps outside my va jay-jay it's not painful. I don't know if its the shaving. This has never happened to me or if its the pregnancy I'm 9 weeks. I don't have a lot of them it's not like I'm cover in them. It's not painful or itchy.

Next time I think I'll tell my ob but any thoughts why I may have them or gotten them?

Sorry for the too much info
