Period 5 days late

Okay so hey ! Lol my period is 5 days late and I just got my iud token out in February. Do you think it could be that? I had a drunk night with this guy I’ve been talking to. He used a condom at first but I think he took it off can’t really remember. I logged that I had sex that day and turns out I was 13% fertile that day and 27% the next. I’m freaking out. My boobs have been really sensitive and sore and I gained like 2 pounds And it stayed ( which it’s super hard for me) I pee a lot but I think that’s because of a uti I had but I think it’s clearing up. I’ve been pregnant before and these were my same symptoms but I didn’t take a test till 2 weeks after my missed period. I just need someone to tell me I’m overreacting and just stressed.
