What are the chances of me getting pregnant on the day I ovulate with no egg white cm??

Ashley
So I can feel when I ovulate cramps on one side etc.. I had intercourse for the past 3-4 days I ovulated yesterday. BUT, here's the kicker.. I don't get the end white fertile cm and if I do it's slim to none, to where I don't ever see it. What are the chances of me being able to get pregnant? I already have 2 boys but me and my SO are trying for another and it's not happening! Help please?
