CM question

Bee
So, 
​I know that period trackers don't always work, but I still try to use them just to get an estimate on when I might ovulate, and it told me that I would ovulate on the 14th so my husband and I had intercourse the 13th, today I am expierncing the "egg white" CM they say is the best and most fertile CM, I was wondering if that means I'm ovulating today and if I am is there still a possibility I could be pregnant from just having intercourse the 13th? And if I were to get pregnant would the CM stop?
