Hello everyone, 23 weeks pregnant, the baby has been still for two day…

Hello everyone, 23 weeks pregnant, the baby has been still for two days now. I'm noticing it and my doctors said there is a late risk, so I need to stay home and rest. Everything was good before but he's not moving anymore. It's really scary today. I checked, he doesn't move at all. He just pinches a little bit. Is this normal? This is my second pregnancy. When I got pregnant the first time, I had a miscarriage in the first trimester. I'm very worried. Give me some advice!?
