Need some help....

Shauna • Wife and mother of 4 beautiful kids, trying for one more. :)

This is our first month trying, I'm supposed to ovulate this coming Tuesday, but today I got ewcm....

How many days before you ladies get a positive opk, does your cm strt changing... I hadn't planned on doing any opks, bc we are trying to gender sway and are supposed to stop bd'ing 3 days before O.

Advice is appreciated.

Thanks. :)
