BBT help

Jada

I'm new to bbt charting and I should've done so earlier in my fertile week/cycle but I really can't tell when I ovulated or if. I had ewcm on the 16th and proceeded to be watery until the 18th. My premom app says I ovulate the 19th while glow says the 18th. I had the most watery cm on the 18th along with the twinges on my side. What do you think? I'm really praying we fall pregnant this cycle 🥺
