To all you BBT experts..

Becca • TTC #2, PCOS, on metformin

I'm a total noob with BBT. I know to take it before I get out of bed or do anything, but does the overall temperature of the room or the clothing I wear make a difference? Bedroom is always cold because that's how me and my husband sleep best. Sometimes I wear clothes and sometimes I free-boob it.. Does any of that matter?
