So to start, I suffer with really bad health anxiety. Only a month or so ago I had all my bloods checked, stool sample and an ecg (only a short one) because of my extreme PMS symptoms (extreme fatigue, bloat, panic, nausea, dissociation etc) and everything came back normal... I haven't worn my Apple Watch for the last month and had been feeling so much better and less anxious however I want to track my steps so put it back on yesterday. I am on my period and also fighting a bug - but feeling completely exhausted, the most extreme tiredness I've had. I've had coke and a coffee and don't usually have caffeine to try and keep me awake. My resting heart rate is 70 today which is higher for me however I've noticed two sips of 47/50 when I would have been resting...?! Is this something you would be worried about? Not sure whether to hassle the doctor... my heart rate is going up and down as normal.
