Decreased movement at 38+1?

I know babies don't move as much when you hit 37+ weeks but when should i get worried?

Some days baby girl is a jumping bean and other days shes pretty Lazy, honestly 5/7 days she's pretty lazy but I can get a few movements in a row.

Today I felt her after eating and occasionally but after not feeling anything for a while, I tried to do kick counts and it took her 26 minutes to get to 10 movements and that was with me moving around to feel her and pushing on my stomach a little bit. When do i need to go to L&D for decreased movement?

I've tried drinking cold liquid and eating something sweet, moving around and putting my hands on my stomach. I have like no bump and carry her very close to my back.

Edit to add : they aren't big movements, they're faint with a few kicks and noticeable movements in between.
