Scared !!!

I had sex three times last week, each time we used a condom and it was on the last day of my period and the day after. We checked the condom every time and it never broke. But now I am having to pee SO much, it feels like a UTI, and i’ve been bloated. I know that frequent urination can come with pregnancy. I’ve been on antibiotic for UTI for 2 days and it hasn’t really helped. I’m scared I could be pregnant but I dont know how I could be given no sperm ever touched my vagina?? He always pulled out before he came and i would give him a blowjob till he came in my mouth. I am supposed to start my period in 2 weeks.
