Hi, I am 21 Years Old. Could dry humping, lead to pregnancy if I was wearing my thin layer of panties and my boyfriend, his thick panties? I have this doubt because both of us were wet and our underpants were too. But after he had ejaculated, within two minutes, I had changed my panties and washed off. I am really scared if it could lead to pregnancy, and if so what are the ways I could prevent it from happening ? Please Help. I had my last period on the 1st of March, and I am ovulating now as of today. Please tell me.
