STD testing?

Hi so I’m turning 18 in two months and obviously had sex. The thing is I’ve went through my “ hoe” stage last week I slept with two guys at different occasions. And we’ve used a condom but my friend recently found out she got a STD but didn’t use a condom! Idk I’m really paranoid and it’s probably for no reason because I’m up to date on my shots and I’ve always used a condom and the boys also got checked! I can’t go planned parenthood because it’s expensive in my area and my mom won’t give me my insurance card. I would tell my mom but she one of those strict parents... so I was wondering if anyone could give me advice ? I don’t have any symptoms and I always pee right after and use protection
