Confused?

Okay so a condom broke during my period, and he ended up finishing inside of me. About a few days after lasting about a week I had like dull cramps, I’ve been nauseous and having cloudy pee but no burning. I’ve had plenty of uti’s and there’s no burning or anything associated with a uti besides cloudy pee and that’s off and on. I’ve been drinking water and stuff and taking vitamins and the cloudyness only seems to happen when I don’t drink enough water. Having dull lower backaches though and the cramping is off and on at this point. I also usually get cysts so I’m assuming it’s that, but part of me worries that it could be pregnancy. I’ve heard from sex Ed teachers that even on your period it’s possible to get pregnant, but I’ve heard elsewhere that that’s not possible. Can I get some clarification? I’m going to urgent care p soon to figure out if it’s a uti or not. But I’m asking about the other symptoms. Thank you in advance!
