Fitbit and ovulation?

Amanda C

So this is interesting. On the left is the chart of my testing heart rate from the month we conceived our angel baby. On the right is this month. This is the first month I have had a "dip" in my heart rate since we lost our Bub at 17 weeks. I am hoping this means I ovulated. I don't even really care if I got pregnant this cycle but it would be nice of this means I will get a period soon.... Still waiting for one at 9 weeks post d&e.

Anyone else wear a fitbit and track ovulation? I would be curious to see other comparison graphs.
