Should I be worried?!

Leah • Mom of 2 boys. Sage due 08/23/15. 🎀
I was sitting up on the couch, with my hands over my stomach like usual when my brother came home with his 60-75lb pit bull Molly. Who jumped onto me. I tried to keep my stomach covered but she practically used it like a springboard, jumping up onto it and then using it to jump right back off. And it happened directly  where baby Sage is. I don't feel her throughout the day, only during certain times in the day (after drinking tea and before I fall asleep as I'm laying down). It does hurt a little bit where she jumped on me but should I be worried? I know the baby is well protected but I've been super protective of this little one compared to my two previous pregnancies. Any help or suggestions would be greatly appreciated. Thanks so much. 🎀
