I know everyone on here is looking for the earliest sign that they were successful. I just wanted to share my experience. My early symptoms felt just like PMS but there was one big difference that O wouldn’t have known with out my Fitbit. My resting heart rate jumped from right around 60 bpm to 70 bpm like over night.

I got my BFP on 8/3 before that my tests were all negative. But my heart rate started to rise steadily after ovulation on July 20th. Just thought I would share.
