Pp bleeding

Christina
Hi mommy of four little ones. My youngest is two months old. 
A few weeks ago I picked up my three year old. Who fell. I had a gush of blood come out and had bad cramping. I told my ob about this a few days later and she said pick up anything heavy a cause it and not it lift anything over the weight of my baby for a few more weeks. 
So middle of the night my three year old falls out of bed. I pick her up and yet again another gush but this time it bleeds for hours and has clots. Should I be worried? It's finally slowing down but my lower belly hurts like someone punched me.
