Ovulation CM

So this might be a little TMI. But ever since giving birth to my son in Aug 2020, I started having random yellow ish discharge. I was tested multiple times for infections ect and it always came back clear.

Now that I’m trying to conceive again I’ve connected the fact that the yellowish discharge literally only comes when I’m ovulating. It’s so exact I wouldn’t even need to take OPKs anymore to tell me I ovulating. Does anyone else have this ? Does it sound normal
