What is happening.?

Ta

Okk. So, to start from the beginning..I am 2 months Postpartum and haven't gotten my first period after yet. My husband and I had a "Oops" about a month ago. A week ago my OB did a blood pregnancy test (because he was concerned that I hadn't gotten my period yet)..well it was negative (thank goodness!)

Anyway, ever since our "Oops" I have been tracking my BBT and it looks like this..

And I have been seeing a significant rise in my Resting Heart Rate (with my Fitbit) that looks like this. It went from 66 bpm on July 9th to 79 bpm today (July 26).

Does anyone know what is happening.?
