Could I?

I had my period from September 19th to October 28th (irregular periods). I had unprotected sex during that period and everyday of November expected 2 days where I didn’t have sex. I spotted light pink on the 10th, 11th and 13th of November and also I’ve been having pregnancy symptoms but I also have a bladder infection so the symptoms could be from that. Anyways I want to know if anybody think I could be pregnant?

I don’t want to test until December but I want to know if I should even test.
