If the baby is moving it's a great sign. Not to worry you, but they do say monitor change in movement, not just "no movement". So it's a wise idea to speak to someone. I panicked the other day, so I know how you feel, Elliott.
Also, the baby could've changed position, that's why you might be feeling reduced movement. Don't panic. Speak to someone in the morning if you're still concerned. That's what those people get paid for!
