Aih, nadi 100+ when you're active is normal lah, tapi kalau consistently high even when resting, better check with your doctor to be safe especially since you're worrying about it. A few of us mummies pun ada yang notice nadi naik when stressed or busy with the kids, tapi once we relax memang turun balik, so kalau yours drops to 96 when you're calm, that's a good sign. Just keep an eye lah, and if it stays high even when you're sitting down doing nothing, definitely go see your GP, okay? Could be nothing serious but better to rule out anything, kan.
