Surprise surprise

Well, I’m 11 days late, i keep testing but keep getting negative results, i feel so bloated and my head was hurting for like 2 weeks straight. I ovulated the 7th of April which that whole week i had unprotected sex and almost every other day, even though he pulled out, which i know has the same risk. I’m not saying i don’t want to be pregnant, i just don’t know what to do or what to test with, cause i feel like they’re all going to be negative.
