Almost 28 weeks. Lack of fetal movement.

I’ll be 28 weeks on Monday and I felt the baby move early this morning. Since then I’ve eaten ALOT and kindve feel like I might have put her in a food coma considering I haven’t felt her move anymore today besides one tiny flutter. She’s normally very active. I’ve tried the cold water and laying down thing too and only got the tiny flutter. Normally if I just lay down she goes crazy kicking. I go tomorrow for a check up. Anybody else experience this? Put some ease to my mind please. Also I don’t normally eat this much, today I’ve been nonstop.
