They can grimace and smile in the womb and can dream as they have REM sleep, 4D pics have shown this, but not cry. In fact some babies are 3 months old before they cry tears because the tear ducts are not always even developed at birth. so if they cant make noise and they cant shead tears they cant be crying. In order to feel upset though they would have to experience living, so any emotions they feel in the womb are very basic, like pain or discomfort or shock etc, more reactions that emotions.
