Might be pregnant, not sure.

I've had unprotected sex a few times and my body has just been feeling off. He always pulled out, put tonight he didn't. For about a week almost two weeks now I've broken out with acne waaaay more than I normally do. And even when j do break out its when I'm on my period which I should start til the end of next week. I've been feeling sick but I don't want to assume I'm pregnant. Please tell me the symptoms you had before figuring out you were pregnant!
