Re: xpost: calling all BBT experts: thermometer question
remember all kinds of things affect bbt like stress or sleep. also remember sometimes you dont have it on the exact same place in your mouth. I put the thermometer on both sides under my tongue so I def. have it positioned correctly at least 1 time. If the reading looks suspicious I take it again. If it still looks suspicious I see what happens the next day or the third day. I also check CM and that usually settles it. some cycles you know which day you ovulated and some cycles your trying to decide on 2 or 3 days. so err on the side of caution. keep using the old one although does it really matter? I only take my temp for a week or so just to confirm ovulation that way I dont get too overwhelmed by the process.
