Grandma pushed on my belly really hard

Baby was kicking and so I asked my mom if she wanted to feel. When she came over she pushed so hard on my belly that I felt her push the baby in me (if that makes sense). It hurt and I could feel pain in my back. It's been a few days, baby is still moving normally, but I'm just nervous she hurt him and will cause some sort of delay in his growth. Anyone else experience anything like this?
