For those who have experienced decreased fetal movement, how long did you wait before you went to the ER? I woke up several times last night on my back (my hips we're hurting really bad) and today he has not moved as much. I've felt slight movements but no kicks or anything big. I'm 37w today so I know he's also getting pretty big in there. Should I be worried? I have an appointment tomorrow at that seems like a long time to play the wait and see....
