Hi I am just learning about when I actually ovulate and so forth. I have started charting but I have 2 problems.

a) My AF is irregular but the ave length is 35days (when it suits it)

b) I work nightshifts...

Now my nightshifts are all over the place but I generally work 3-4 nightshifts a week. It is going to be really difficult for me to take my BBT at the same time after having more than 3hrs sleep. I am not quite sure what to do and will this adversely affect my temp results?

The only plan I have right now is to take my BBT at the same time in the morning when I am not working nightshift and at the same time in the afternoon after I have slept following a nightshift. Would this still work?

Thank you!
