Wreck while pregnant

So, I'm 24 weeks pregnant and on the way back from Missouri a semi truck tried to run us off the road, but didn't. Just shook us up a little. Then he pulled off on a side road and we kept driving. So we got his plates and his company name. We made it about 4-5 miles down the road and he (same guy) comes flying by about 90 miles an hour and then gets in front of us and slows down to about 50 and we got his trailer number, and like 6 cars went around him and we were gonna go to pass him, and we got to about his door, like up enough he could see us, he starts getting over and switching lanes and run us off the road and we hit the ditch and bottom out really bad. A semi stopped because he saw it all and wanted to see if we were okay. Then two highway patrols pull up and see what happened and send out a broadcast to stop him in the town up, because he kept speeding by. They took his information and asked if we were okay to drive and I said yeah and drove to a rest stop up the road about 3 miles then went home. I was still crying because we just got our car 2 days ago, and I was worried about Elliot and my wife and dog and my friend. So we drove to my Nanas and my nana was like go to the hospital since you haven't felt him move and are hurting a little.  So we're at the hospital and baby's heartbeat sounds good and they think he's okay so we are getting sent home. So hopefully something gets settled soon. Because he could of killed my wife,friend, son and dog and myself. All because he wasn't paying attention and we called his company to get him in trouble.
