I'm such an idiot

Me and This guy that I've been talking to for like a month now have been hanging out lately. Today was the second time and we had sex. I feel like such a whore because I know my morals and that I wouldn't do that but he kept persisting so I gave in. We also didn't use a condom..he didn't cum in me but I forgot about precum. Does anyone know if precum is actually that effective to get someone pregnant? Any morning after pill suggestions they're quite expensive :/
