Is it normal to not feel my baby move for a day?

Depends. It depends on how far along you are. Most women feel movment first at 18-20 weeks. From there until about 30 weeks fetal movements may not be regular and you may not feel them every day. After 30 weeks, you should feel your baby move every day. If you are ever worried it is easier and safer to get checked then to stay at home wondering.
FETAL MOVEMENT. As soon as the baby starts moving and no movement felt for one day, you have to consult your OB for any problems at once.
