Am I pregnant?!?

So I hooked up with someone on the 15 and 16th this month (June), on the 15th he didn’t where a condom and I didn’t take plan B I’m also not on any birth control. He pulled out and his orgasm was a bit delayed so I felt when he let out on my thigh. The next day, 16th, he wore a condom and came in the condom. My fertility levels are low but I get my period in 3-5 days. I’ve also noticed that I started bleeding/spotting when I pee and that when I pee it burns. I’m pretty sure this is uti though. There has been no discharge in my underwear since we had sex. Is it possible that I am pregnant!!!!?
