Cervical mucus question...

I recieved a positive opk on 1/7 (cycle day 20) and today (cd 27) I'm feeling wet below and checked and it's like lotiony white slightly stretchy. I'm wondering if I should have sex tonight in case something is going on in there. But it's def white so I don't think it fertile cm and I already surged. Does anyone know of this is a sign of early pregnancy or sadly of af? I took clomid and dexamethasone this cycle. This am I got a bfn.
