Hi, I Have Two Small Pimple Like Bumps On The

Hi, I have two small pimple like bumps on the left side of my labia minora. They are not inside but outside. And they are filled with blood. They dont hurt unless I touch them. And they appeared two days after I shaved. But I did have protected sex a couple days before. I just had a baby 4 months ago so it was my fist time shaving in 3,months. Please help
