Because of the stress, you may not be as focused on when the baby moves. Your mind is on other things, so you may not be paying attention when it happens. I recommend drinking some juice or soda and then go sit and relax, see if you can get that little one moving to help ease your nerves. It's a little early to start kick counts, but try to relax every night and spend some time with baby. Rubbing your belly and talking sometimes helps to get the baby moving. It's get bonding for you and baby, plus it will help you feel better about the baby's health. If your still concern then, contact your provider.
I would make an appointment with your ob just to make sure because im 12weeks and 5 days today and my baby moves like crazy mainly when I want to sleep
i am 25 weeks and baby moves alot. My midwife said if there is a change in babys movement you should contact the hospital. Last week i didn't feel her move all evening when she is usually active and was about to call the hospital when she started to move again.
I think if you are stressed maybe you are just not noticing the movement as much as your mind is somewhere else....
