Update on almost crash

So I had posted earlier about how I almost got into an accident the only thing that happened was the car spun until we finally slide into a little hole type area. I didn't have my seat belt on (very stupid I know) but by the grace of god I didn't fling out my seat or hit my belly or anything. The only thing that's wrong is my back hurts and my stomach. I'm 27 weeks pregnant and trying to avoid the doctors so if someone could help me it'd be great
