2 DPO... NEED HELP/ADVICE PLEASE ❤

Ola

AF isn't due until 09/19 and just had went through my fertile period in which my SO and I BD every day. Normally if AF is on its way my CM usually dries up, becomes tacky. However when I checked today (2DPO), my CM looked like this and since seeing it this morning I've checked twice with the same results. Now I have to wear a panty liner. Can someone tell me if this has happened to them before and what can it possibly be? Please and thank you ❤
