Thermometer Question

I'm a little confused- are you supposed to chart to the 10th (97.2) or 100th (97.24) degree? I found a thermometer online that had good reviews, but it only charts to the 10th and I remember reading (online? in a book? eh, somewhere) that BBT charting needs to be to the 100th degree.

Anyone know which is correct? What do/did y'all use?

  2. I have been charting since June 2009 and the one I use goes to the 10th degree...it was from babyhopes.com I think. I use fertilityfriend.com to chart it on a daily basis...I started off with paper charts but the cost of using the site is small and it charts your coverline and makes projections based on the information you enter. I ovulate on day 15 or 16 over 90% of the time so it makes it a lot easier for when planning ahead for the IUI's. Hope that is helpful. check out the website, lots of good info! ~Wren
