me and a guy where messing around a couple days ago (Monday to be exact) he was wearing boxers and gym shorts and i was wearing just pajama bottoms (like the cotton ones from old navy)i'm just worried sperm got inside me somehow, he said he didn't ejaculate but i felt something wet like near my crotch don't know if it was me or from him. Even if he did ejaculate and lied cold i have gotten pregnant from it? Help i'm really worried not trying sound dumb or anything. I.m also on nexplanon (birth control implant) have been for 7 months will be 8 months tomorrow. Also i have a metallically taste in my mouth but it on one side of my cheek  inside, I think its from using cinnamon toothpaste because it started happening right after I brushed my teeth.
