7dpo with uti?

I am on my two week wait af should arrive June 1st. So I am currently 6/7 dpo

Last night had lower ab pain /cramping, that lasted 4 hours

This morning woke up with this urge to pee and uti (urinary tract infection) symptoms.

I m scared to take antibiotics if I could be pregnant. Help! Any advice?

Has this happened to anyone?
