we were messing around, I am virgin, he came in my mouth, I have white discharge

 New  Reply as guest I am 18 years old and a virgin. My boyfriend and I were messing around and I went down on him, and after he came(I swallowed) we grinded, but without clothes. This is the first time I have ever done anything this intimate, so maybe I am just paranoid, but could I get pregnant from this? He came in my mouth, and then he dried off and we proceeded to grind...he was never in my vagina, not even slightly, just on the outside and around the top of my clitoris. Like I said I've never done anything this intimate so I may just be paranoid, but answers are greatly appreciated! It has been a week and I am not experiencing cramps, but I do have a white discharge that looks a little bit like ejaculate, and smells sharp. No pain or itching. What is it?
