Why won't my temperature change?!

Emely

Why is my temperature the same every morning?! It's consistently staying around 97.41!!

Thermometer: purchased from Amazon about 3 months ago. I've also tried the thermometer other times of the day and it gives a different reading.

OPK: Clear Blue Advanced Digital said my peak was on CD16 it is now CD19.

Anyone have any idea what might be going on? This our first month seriously trying :(
