Thanks

The BBT is the only thermometer we have in the house, so i'm not sure how DB would feel if he woke up to find me putting it up there!
I've just started a new cycle, so I'll see how the temps are this month, then i'll switch to vag if the temps are still over the place.
Is there such a thing as normal varience? Are normal temps within a 1-2 degree range until a thermal shift happens?
