I am 28 weeks and 4 days, last week I saw my baby and he was fine. healthy. For the past two days and today he hasn't been as active but I've been really busy so I dont know it is just that. Last night he was active and throughout some of the night, as of this morning until now I've noticed I haven't felt him. I'm heading to school and wont be able to be home to lay down and feel him until another 2 hours. Is it normal? should I be concerned?
