My DD's godmother fell on her tummy when heavily pg with her DS who is 21 so i am going back a long time but it is a story she tells often. She fell down a whole flight of stairs. She was taken to hosp and they couldnt find a HB for the bub. They were about to induce her when a student midwife used one of the old fashioned horns and found the HB, she said she was still very worried though it was up there with one of the best moments of her life. She went into labor naturally within the next week and had a H&H boy!! i'm sure your friend will be fine too. Babies have lots of fluid remember to cushion them. i am sending you both a big though and hope you are both feeling a little better.
