EWCM after ovulation?

Britney

So I normally ovulate around cycle day 15/16 and I think I did this cycle as well but I ran out of tests and got my new ones in yesterday. I was using clear blue digital advanced and got a high reading the 15th-18th before I ran out. I am on cycle day 19 and the last two or three days have had a lot of EWCM which I thought only happened right before ovulation. I’m still taking ovulation tests and they’ve been negative so I’m wondering if I’m just going to ovulate later this cycle or not sure what’s going on. What do y’all think?
