Made a post previously because I thought my thermometer was possibly faulty because I had gotten basically the same temp 4 days in a row. The fifth day it did show a higher reading but then the next four days up to today it is now stuck at 97.9. The first four days it happened I tested it in the middle of the afternoon and did get different temps but just decided to test it again - took my temp twice back to back and still got 97.90. Its 10:30 at night and I've been up all day. My other basic thermometer read 98.4 back to back. So I'm going to guess my BBT is faulty?!

Btw the BBT is the one from target and I did read it's known to favor temps.

Can anyone recommend a good reliable thermometer?!
