I Need Help!😪

Does a UTI after ovulation a few days before your expected period a sure sign you're pregnant? I have had UTI's before, I know how they feel and what they are. This one seems pretty severe and I am taking AZO at the moment and drinking a bunch of water and holding I can clear it up on my own because I have before. This month I didn't have sex at all besides anal but there was some genital grinding/rubbing. I follow FAM but when I was ovulating I am scared that at one point there was potential precum on my boyfriends fingers that were then inserted into me. Both times there was genital contact i wasn't ovulating according to GLOW. One of the times I was on my period and the other time was the 29th-my period is due on the 4th. I have the same PMS symptoms I always do but at the same time this UTI and my anxiety are freaking me out...
