Bumps on my vagina???

Chloe
I have these two small bumps right by the opening of my vagina and I thought they were pimples but they seem to be crater-like. They're a bit painful and white ish and about the size of a pin head. It shouldn't be an STD because my boyfriend and I had never had sex or done anything sexual before each other. What could it be and how can I get rid of it?
