Get over your embarrassment and being scared...

You need to be seen and in the meantime, no sexual encounters until you know what you've got, get on a treatment plan, etc...

Do these bumps come and go? Burn, itch? Do they have an appearance of blisters or warts? Do they scab, heal and go away? Do you have these anywhere else on your body?

they are just like half bubbles on my skin they dont burn or itch they hurt if pressed on they feel like pimples but i dont know... and yes they come and go i can go a really long time without getting one. When i got pregnant i was tested and i always figured that whatever it was if it was anything my dr would have told me especially since i had one during my pregnancy... and yeah they kind of scab just like a pimple

I would go back to the doctor and have it checked out...probably be best until you get another one so there is a visual as well as maybe they will take a culture to find out what it is.

Since you had one during your pregnancy your doctor may or may not have noticed or thought maybe you already knew what it is... you never know what goes on in their minds...
