Got into a car accident in our truck, the lady behind us got hit from behind and ran into our hitch no damage to our vehicle and I seen it coming but we couldn't get out of way so I prepared myself and made sure seat belt wasn't tight against my belly it was underneath my belly. She didn't hit us super hard just enough to jult us good but now I'm worried about my daughter I have felt her but to me hasn't seemed like AS much as I normally do. I think I am over thinking it I have no cramping or pain no blood just my mind keeps thinking what if something's wrong. Ahhhh need to clear my head !!!
