Help please ( ovulation )

mary

Hi everyone please I really need some advice as this is really really starting to stress me out, according to my app’s my ovulation day is meant to start soon, 1 app says it starts tomorrow and this app says I will ovulate on Monday. I’ve been doing testing and BBT EVERYDAY and still all is the same. Tested a few different (6) in total ovulation tests and all is saying negative, if I am to ovulation in the next 1 or 2 shouldn’t I at least start to see some positive test’s, I am really starting to stress a lot about this as all of them is coming back negative.. any advice would be helpful please have this happened to anyone else and still ovulated …
