Ovulation info

Madison • Second time round let`s do this!!
Trying to figure out if it's possible to conceive.
So on Friday I had O pains... 
Saturday I had a lot of EWCM
Sunday I had a lot of EWCM again 
And then we had sex this morning (Tuesday) and now I've got some more lower pain happening. 
My cycle is still very irregular since having my first son still.
I just don't know if you ovulate before or after pain and mucus??
