Peeing a lot!!

I have been peeing a lot! Like every time I pee I have to go the next 10 min. It's been happening for 3 days now. I ha sex with my BF 3 weeks ago without a condom he didn't cum in me but yes I know about precum): but I have just started to pee a lot bu I don't know if it's just has to do with my stress about being pregnant cause I heard anxiety and stress can freak out your bladder. Any advice?!
