Period advice please

Ok soooo my period is going on 3 days late. I had sex two weeks ago with a condom and there was absolutely no rips or tears. We checked with water and yes it was pretty gross. I've been stressed and kinda sick. I think I might even have a small uti. Should I just wait it out? Thank you!!!!

Update: I took the test this morning and it was negative. I guess I'm just late this month
