How far along are you? I doubt it did any harm to your baby. Your baby is pretty protected in there. If you experience bleeding or cramping call your doctor. I was hit in the stomach by accident one day but my baby is just fine. If you are really concerned call your dr and see what they say. Good luck.
I have ultrasounds twice a week and my little man hates them! And he won't move or do what he needs to so the ultrasound lady pushes on my belly(REALLY HARD) I don't think you have anything to worry about. They are professionals and they are rough on my belly.
My midwife regularly pressed down on my belly to fee where baby was and where his head and but was. And he came out fine. I honk you'll be ok
