Has anyone else little on stopped moving so much at 30 weeks? My little man has calmed way down to a worrisome point. If I push on the tummy he will move a little but not the way he has been a few days ago. Should I be worried or is this normal

***UPDATE***

So I went to the doctor after calling them. They told me to come in. He was fine just dropped low and was in a ball. He moved a little bit but his heart rate was fine. He just had a lazy day. Today he is back to his normal super active self. They told me better safe than sorry and it was best to come get checked. I have my actual appointment tomorrow and they will give me his growth rate from 2 weeks ago.
