I was in the backseat trying to get my 40lbs toddler into his car seat when I slipped off the backseat and fell onto the floor of the car. I ended up falling crouched up, and my son fell onto my stomach when I fell. I had to scream for help for a few minutes before my mom heard me and was able to come help us out, because we were both stuck crouched up in between the back of the drivers seat, and my legs were in the air against the front of the backseat. This happened around 11:30am, it's now almost 9:30pm and I have been in quite a bit of pain since, and it seems to be getting worse. My back hurts, but the front half on the left side of my stomach is very sore with burning/stabbing pains also. My baby has been moving about the same, but I was wondering if I should get checked out at the hospital just in case.
