Decreased fetal movement at 33 weeks

Manon

I’m 33 weeks and 5 days. FTM. Since last night, I noticed that my little one hasn’t been moving as frequently as he/she has been. Knowing my body, it’s out of the norm. I’ve only felt a few. I ate lunch, didn’t feel any. About an hour or two later, I drank orange juice, but shortly after only experienced maybe 4 noticeable movements. Usually little one moves like crazy, especially when I poke my belly. I’m nervous. Idk what to do. If I don’t feel much after dinner, should I go straight to the hospital? I’m just starting to get nervous.
