I have been my first PEAK reading on my ClearBlue digital OPK on CD19 (5/28) and had a dio in my temp.. my temp did rise on 5/29 but not a huge amount and went down 0.17 today.. I follow the Femometer app since I have their thermometer.. it told me to test every 4 hours until I got high or low reading.. well with the ClearBlue digital advanced, once you get your peak, you can’t use the device for 48 hours.. so I took one today just to make sure it went down and I got another peak.. should I be concerned?? I was going to continue to monitor my temps regardless.. thank you for your help!
