Alhamdulillah you're okay sudah! Honestly the movement thing after covid boleh jadi normal, our bodies memang need time to recover fully, and kalau nutrition kurang during recovery period tu boleh affect energy levels of the baby juga. A few of my mum friends had the same worry after they kena covid, tapi movement came back macam normal once they really focused on eating well again, protein, iron, lots of fluids. But since you're already past the acute phase, I think best to mention this to your doctor at your next scan or checkup, just so they can listen to the baby properly and ease your mind, okay?
