Question about CM, possibly tmi

So I'm typically a person who does not have a lot of CM even when ovulating, the reason behind my dr suggesting we use preseed. I also don't have any discharge in my underpants, like ever. If I do, it's very very light and only happens maybe once. Since Tuesday, the day after I ovulated, I've noticed a larger amount of creamy discharge every day and every time I go to the bathroom. Like I said, I've never had discharge, the only way I would know what CM I have is by actively checking it, and even then I have a very light amount.

Could this be a good sign?
