Confused...advice please.

I use Ovia and Glow. Glow says I'm on my peak day in my fertile window and that my period should come the 23rd and then Ovia says I am supposed to be starting my period today. So far no sign of my period and we had sex last night so I can't check my CM to see if it's fertile. I had some cramping yesterday but chocked it up to ovulation and hunger. I just don't know if I should wait to test on the 23rd like I planned or trust Ovia and of my period doesn't come this week treat it like a missed one. Just so confused! I've been feeling off for a week or so. Increased appetite, increased sense of smell, little pinching feeling in lower abdomen/uterus area, fatigue, dizziness, nausea yesterday in the car which never happens...I just don't want to test and get my hopes up.
