Not sure if this helps or not and I know you are on a new cycle, but thought I'd answer anyway.
1) remember positive stress can delay things too.
2) I KNOW mine cervix stayed high the whole time. It never lowered and then raised. (I only know this with Faith.)
3) Although I never used a monitor, I used Ovulation tests for a few months when we first started TTC with Faith and I never got a positive test. Although probably COMPLETELY different than the monitor, I read something ONE time and I don't remember where, but it said that it can have something to do with hormones. So if this cycle ends up wacky I'd talk to the doctor as you have already said you would.
