Ewcm for 16 days?? After 4 months of just creamy?

Im 34 ttc#1. I was on bc pills for 16yrs. I got off 6 months ago. I had vag ultra sound and blood work all came back good. I only had 1 real period 91days ago. Since stopping bc I've only had thick creamy cm. Well 16 days ago I finally got ewcm but I still have it. I got a pos opk March 25, 16 days ago but I got another pos opk April 3rd. I don't think I ovulated as I would either have my period by now or a bfp which I don't.

Anyways is having 16 days of ewcm normal or maybe normal after bc??
