My boyfriend and I have had sex three times within the last month and I'm kind of worried if I'm pregnant. The first time it was without protection but he pulled out. About two weeks later we had protected sex, fell asleep, then woke up and had unprotected sex but he still pulled out. I have an irregular period so idk if I should have gotten it by now or not. Right now I've been feeling really tired for no reason and my lower stomach area feels really bloated. Any thoughts?
