Wild night pregnancy

Me and my boo had a wild night😂. He came over and we watched a movie before I knew it we were having sex. He was drinking before hand. I got on top and rode him and he cum inside of me wasn’t expecting it . He said he got majority of cum out but still had a little left in him and wanted to get the rest out I didn’t even know that possible.

Is there any chance I could be pregnant this was during my fertile week I’m sure I saw egg white mucus a few hours before

Ps. If I’m pregnant I’m pregnant we’re not upset😂
