Re: please advise
Have you tried eating something sweet? Usually that will bring about some movement from the little one. Try not to get too nervous. Maybe the baby is just napping or feeling lazy today. Just like us, they have their unactive days as well. Yesterday I didn't feel my baby move much at all (I'm 21 weeks along) & today my little guy is moving about a lot, just like normal. I'm sure all is fine.
If you are really stressing out though, you can always call your dr's office & express your concerns. Maybe they can get you in for an u/s just to ease your fears. Worrying is not good for you or the baby.
I hope you feel better soon. Keep us posted.
