Why? Am I getting this CM

Brenda

My last cycle started on January 21.  I am currently on   Cycle day 33 today.  All BFNs up until now.but for the past few days I've been having egg white cm and a lot of if.  I keep thinking its AF  and when i run to the bathroom its all this clear slimy cm.  could this be because I am preggers? or could this be in place of AF??
