I think you should call and talk to your midwife if you feel concerned because mom's instincts are usually pretty on point. and if it's nothing it will help your peace of mind in knowing your little one is okay

You should be ok. If you are really concerned you can contact your dr/midwife or l&d for additional information. My little man is due tomorrow and I hardly feel him unless I'm in a certain position, like laying on my left side.

I've been counting and he's had about 4 kicks in the past 3 hours @hennamama

Reduced movement is normal. You can always try to monitor for smaller movements, rolls and small kicks or bumps.
