UTI?......Again? PLEASE HELP

Lizzie

So my partner of about three weeks and I have sex just about every day. Last week I had a UTI. That was weird because I pee right after sex and I even take a quick shower to rinse off. But I got over that, finished the medications for it. Now about a week later, I’m on my period and we just had sex, granted because of tampons it was a little dry. But after sex, I went pee and took a shower. And now it feels like I have ANOTHER UTI only this one just skipped straight to the burning and the urge to pee every 10 seconds. I can’t tell if it’s bloody pee though because of my period. Please if anyone has advice.... I’ll take anything. I’m also a poor college student and I have health insurance but I do still have to pay part of it. And I just don’t have money for a doctors appointment right now.
