Yes let your gynae know. Because it shouldn’t decrease so soon tho! Maybe only at the later part only like week 38-40......
It’s still in the early stages so not to worry. Can check with your gynae in the next visit.
Continue monitoring and see ur doctor soon if it persist for another 1 or 2 days.
Maybe you should call your gyane to voice your concern
Try doing kick counts everyday around the same timing
U can try taking a little sweet drink?
Let you gynae know about it
Speak to gynae asap
Try to sleep on left hand sideways, or lie straight on ur back to feeel more movement
Best to let your gynae knows.. but dun worry it will be fine
