Sharing/ Advice & Thoughts (STD related)

So background, at the end of January I let a guy who I used to talk to about 4 years ago stay the night at my place because he was in town for the night. We caught up with each other and he was telling me about all the dates he had been on and the sex he has had with them. I asked him if he had been tested and he said he recently was and he was good. Well we ended up kissing and touching and he gave me oral but I wasn’t into it and realized that I wasn’t attracted to him anymore. I wanted to stop but he was already too into the mood and kept asking me to put it in and I told him no several times because there was only one person I have intercourse with even though we aren’t on good terms. Well he literally kept ignoring me and forcing himself in me even as I pushed him off. I know it’s my fault for letting things get out of hand and none of it should’ve happened. He didn’t even feel bad that I was crying while he was in me until after…

Anyways I have been good and balanced down there. Literally no issues at all. My period in February was normal but this month my period seemed off. It was heavier than usual in the middle (heavy for like 3 days) to the point it worried me. There was a lot of clots this time and although it lasted the full 7 days, which is normal for me, it ended yesterday and today I noticed blood in my underwear and when I wiped. I can tell that it’s not period blood because of how bright it is. Google says chlamydia causes abnormal bleeding but also says it’s sometimes normal to bleed even once your period ends. I want to get tested but the Planned Parenthood Near me doesn’t have any appointments for 3 weeks. I’m going to go to urgent care tomorrow but until then I’m just worried and so upset that this even happened. Idk if urgent care will even be able to help me.

Thoughts? Any advice on if it could be an STD?
