Two days after my period ended, my boyfriend and I were fooling around. We did shallow penetration, I cummed, he didn't. He said he didn't pre-cum; I bled. We are both virgins: I am 18, he's 20.

Ever since, I have had a creamy white discharge, have been irritable, slight back pain, feeling of nausea, and am tired a lot.

Been reading up on chances of pregnancy but am too scared to take a pregnancy test. My period is scheduled for the third.

Any advice?
