should I be worried

Louise
I'm 27+3 weeks and today I went to the park with my 4 year old son he has developmental delays so makes things more challenging. It was time to leave the park and put up a big tantrum and I tripped over on the side of my stomach, then my son quickly ran bak to the park as he didn't want to leave so I had to go follow him and try to catch him wich is difficult then I slipped down a small slop on the side of my belly again I didnt hurt but just made me very worried. A man saw me in need of help and offered to help me catch my son as I was not physically able to chase him and by this point I was very tired and annoyed he managed to help get my son and then me and my son walked back to the car my son is very physically strong so it took some effort got bak to car and went home. And relaxed in bed for a little bit I can feel my baby moving as normal but still I worry could I have hurt him when I fell over twice should I be worried?
