Ovulation / chances

Please help with advice 😊 I’ve been using clear blue advanced I had a low on the 21st then high from the 22nd to 25th with no peak and now it’s low. Glow says I ovulate the 1st but I think this must be very out. Have any chance with no peak?

This month has sadly drive me crazy everyone seems to be pregnant and I’ve getting very fed up sadly.

Can’t really bd more then above as I work nights so we often don’t cross paths day to day
