Saturday night I was fooling around with my boyfriend, and we were dry humping, he had nothing on, but I had my cotton underwear on. He ejaculated on my underwear mostly where my clitoris is. Is there any chance I can get pregnant? I was on my non fertil days. But I'm sacared because my underwhere was soaked, I don´t know if the sperm reached the entrance of my vagina. I cleaned my self with toilet paper and the underwear to get rid of the moisture, and after one hour and a half or so I took them off. My period is supposed to come in this days, my last period started at sep 14th, but I'm scared. Is there any risk I could get pregnant from this encounter?
