A few days ago I was with my boyfriend and we were laying naked. His penis rubbed against my vagina for a second and it wasn't wet, so I'm not sure if it had anything on it. When I got home that night, I took the plan B pill because I was scared some of his sperm, if he even had any, went into me. It is now like 5 days later or so and I started my period early. My last one was on June 9th and it is June 30th. I've heard that you can have bleeding for a few days and still be pregnant. My question is, am I pregnant if I didn't have sex and still took the plan b pill? And is my period early because of a side effect of the pill?
