Beyond confused!!!! 😓

Ok so I got off my period the week before Valentine's Day weekend... We had gotten drunk we gotten a hotel we wanted to try for baby but we didn't because I wouldn't have been ovulating. I don't remember nor does he remember if he finished in me. With my first child my very first sign of pregnancy was sore breast and that was fairly early I wasn't even a month yet.. So I got home from work, took a shower and realized my breast are beyond sore, everytime I touch them they like tingle and it just hurts so bad to the point where I put on a skin tight tank top so my breast wouldn't be rubbing against any of my shirts. I've been sleepy like crazy whenever I get the chances. I don't know what's going on with me, but my period isn't due until March 12 or sometime around there can anyone tell me if they've had this happen to them and they were really pregnant or what could be going on? Thank you. And forgot to mention I've been cramping like crazy.
