Interpretation of these charts?

Kristina

I use both Glow and Fertility Friend. Glow is showing that I am currently ovulating while FF says a few days ago. BD (or 🎹 piano playing as my husband and I call it). I had my second miscarriage just a month ago but two cycles since. Dr gave clomid for next cycle...my question is what could cause that last dip from today? I’m so confused.
