Help! I don’t know what this is

Soooo I just had a baby 2 months ago. I haven’t had sex since December of 2016. During the last 2 months of my pregnancy I’ve noticed these bumps around my vagina area but it’s somewhat on my ass cheek. It don’t itch and it don’t burn. How do I get rid of it? Do anybody know what this is? Do anybody know the causes? HELP! It’s fucking irritating
