No Triphasic BBT

Ashley

Has anyone been pregnant without a triphasic shift in bbt? I am supposed to start my period today but haven’t had any of the normal symptoms except for a headache. Usually I have bad cramping and the feeling like it is coming. However my temp is hanging around 97.7. My preovulation temp is 97.4 and below.

Here is my chart. The temp taken out is because I was sick and running a high fever.
