No one else to talk to about this...

Not sure where to post this. My SO and I have been TTC for just over a year. We both have Fitbits for his job stay healthy program. My resting heart rate has been going up each day since 3 dpo. I am now still to early to test and my father just passed away yesterday. I’m not to sure on the scientific side of your resting heart rate showing if you are pregnant this early or not. I know stress can cause your heart rate to increase but my father’s death was unexpected and I didn’t know he was sick until he passed. I guess I’m just trying to figure out if I could be pregnant or if anyone else has gone through something similar and found out they were pregnant just after the passing of a loved one?
