help!! idk what's going on

So I had sex this past weekend for the first time(s) in like a month or so. I'm not a newbie at sex but I'm still relatively new about it.
 
I usually get some pretty intense UTI after sex cuz my partner and I like it a little rough, but I usually fix it with some antibiotics pretty quickly. I also started peeing a lot right after sex cuz I thought it would help, but it burned to pee then.
 
However right now I feel kind of like a minor UTI but I'm also continuously bleeding, I think from my vagina. It's hard to control my bladder and it doesn't hurt to pee as I do when I have UTIS. I'm not gushing blood but every time I pee and wipe my toilet paper is like a coral color.
I'm on the implant, got it maybe 2-3 weeks ago. Idk if it's from rough sex or hormonal changes as to why I'm bleeding? Help!
 
Update: it was my period. It was significantly lighter than what I usually have because of the implant. Thanks for the input guys!
