Conception??

Hello! I'm looking for advice and other people's experiences. My fertile window ends in 2 days and my partner and I had sex every single day except for the last 2 days. Immediately after sex I had what seemed like egg white discharge (clear, stretchy, kind of gummy) as well as milky white discharge that's kind of thin. Now I'm having REALLY bad cramping and I'm so confused because it's way too early to be my period. Any thoughts??
