Pregnant and exercise using HRM?

claire_donegal84

I'm getting a Polar ft4 sports watch and HRM for Christmas and I'm wondering if it's ok to use it whilst pregnant? (It's early days, and it was ordered weeks ago). I mean i wonder if it will be accurate at tracking calories burned when exercising, nothing major but mainly brisk walks to stay healthy throughout pregnancy. I'm not sure for how long Into pregnancy it would be comfortable to wear the the monitor but hoping to use it. Any advice appreciated!
