Mucous like discharge

Hi I know most of you are thinking “its fertile discharge you’re fine” but i’ve been having thickish white (not clear like most sites describe) stretchy mucous like discharge for a few weeks now. I have no other symptoms at all and it has no odor and really doesn’t bother me but i’m very attentive to my discharge and sexual health so I’m just wondering if this discharge is just different from what I’ve had before but still normal?

I was just tested for STDs this week which came back negative so it’s not that.

Thank you for any advice
