I myself would go and request a sonogram to make sure baby is okay but i was feeling my son 6 months. They say some don't feel them moving til 5 or evein 6 months.! its whatever. if you would feel better seein ur doctor do so immediatley.
defiantly talk to your doctor. That would scare me too. It is normal to not feel anything til around 6 months. It will feel like butterflies at first then as they grow ,strong kicks that you will dread getting especially at night or when you have to pee.
