Fitbit mommies - resting heart rate

Mónica • Miscarriage June 2018. Expecting rainbow November 2nd

I've been watching my resting hear rate go off the roof lately - pre pregnancy 57/60

Now at 28 weeks it's up to 80 bpm 🙈

to be honest i haven't worked out since I found out I was pregnant - i do have a 1 hour walk in my commute so I figured this would be enough to keep me from becoming a lazy pregnant blob of fat 😅

Any of you have the same?
