me and my partner have been having unprotected sex everyday during my fertile window and after it ended BUT he did NOT ejaculate inside of me . we still continue to have sex but is it possible that i could get pregnant/be pregnant ? i just caught a horrible cold and my nipples are starting to get sore and ive been craving pizza all the time and im a lot angrier now a days . im 7 or 8 dpo .
