CM question & ovulation??

Lexy
Yesterday was my most important day to BD according to the app and then today I felt like I had lots of CM coming out all day. Wasn't creamy so guessing it was clear so is THAT the good CM u need to fall pregnant? 
We have BD past 3 days incl today to make sure we cover everything but just was curious as to know if I was actually o'ing today due to increase CM (I'm not taking OPKs) 
any input appreciated :(
