Am I pregnant?

My boyfriend and I do have unprotected sex, I want to say there's a 70% chance I'm pregnant but I'm not sure because today I am 5 days late but my stomach hurts... Kinda like period cramps but I'm not getting any blood. Also I've been peeing frequently, and my boobs felt very tender for about 2 days now they feel a little bit better. What do you guys think?
