New to BBT

Hi there! I am super new to TTC and have been trying to chart my temp to confirm ovulation. My thermometer came late last cycle so I wasn’t able to confirm ovulation then but I started taking my temps just to see where they sit and I am not noticing a huge temperature shift from the luteal phase of last cycle to the beginning phases of this cycle.

My husbands alarm does go off before mine and I do stir quite a bit in the half hour before mine goes off so I am wondering if that could be affecting my temps or if maybe I am just not ovulating yet? I went of HBC December of 2021 after being on it for 10+years.

Any thoughts or opinions would be greatly appreciated :)
