laparoscopic surgery and cyst removed.. but pregnant?

I have been having bleeding off and on but I have been feeling off.. and moody.. and nauseous at the most random times. smells are getting to me as well.. idk what to do.. whether to buy a cheap test to just be sure. I'm 2 weeks post op. my boyfriend came in me like 2 weeks before the surgery. my uterus wasn't touched and it was too early for them to even see a pregnancy. they did a pregnancy test but I wasn't do for my period for another week and a few days so I know it wouldn't come up..

my question is should I test or just let it go
