You are instructed to start kick counts in your third trimester fir the reasoning of making sure you don't have any decreased fetal movement. If you ever feel that your baby is not moving drink something cold and sweet and that will make the little one jump for joy and start a party.always works for me and I'm 39+weeks
If I were you I would start kick counts until your doctor instructs you to. It may just freak you out even more. I just entered my 3rd trimester as well. As long as you are feeling the baby every few hours, you're good.
You could also drink.something cold and sugary and she should start to move.
You should count your babys kicks. "Its called kick counter" As long as she is making 10 movements in an hour she is fine, if not contact your provider. Plus in the third trimester babys dont have as much room to move around as much, so decreased movements are expected
