I hurt my side while pregnant is my bby okay?

i know how worried you are, i was in a car crash at 19 weeks pregnant and got injured in both my sides, im 21 weeks now and my baby is fine also i fell down the stairs and whacked all my side 2 days ago and my baby is wiggling like mad. how far are you ? if your far even to feel the baby move lay down an wait for a movement, if not go to the doctors, but your baby is very protected with all are layers of skin and then instead a thick womb then inside a big water bubble it would take a very big blow to the belly to cause any serouise danger. as long has your not feeling any pain or no bleeding just go to the doctors and get checked.
