What is going on with me???

Vanessa • The queen 👑 of my castle. Mama of 3 💙💗💗 ttc #4 after a tr 5/15/17 ⭐️

I had my TR May 15, 2017. My periods are always on time, except after the surgery it was late. I've never had a problem with cm. This is my second cycle ttc since surgery. Glow and FF say that I ovulated this past week but I had no EWCM. Ovia says I ovulate in 4 days. I'm so confused. I usually ovulate on cd 15. I'm trying not to use opks because last month I drove myself crazy. Anybody else have a similar experience that can offer some advice??
