Today I hooked up with someone. We didn't have sex, but I gave him a bj and he ate me out and fingered me. I'm not sure if he might've touched his penis with precum on it the fingered me, or made out with me with precut in my mouth then ate me out. I just recently had a scare and don't want another one. According to my period tracker, my period is due in 5 days. I'm planning on getting plan b first thing tomorrow. Do you think I need to? I know it shouldn't be used unless necessary but I'm not sure if I need it or not
