I'm not licensed to practice law in Indiana so what I say here should not be taken as legal advice, but simply as information based on general principles of law which is intended to educate. If you need legal advice, please consult a lawyer who holds Indiana licensure.
It's the burden of the plaintiff in a personal injury case to prove her case "more likely than not." If medical issues are involved, expert testimony on causation is almost always required. Expert testimony on medical issues is expensive: physicians charge hundreds of dollars per hour for their services.
Also, civil lawsuits for personal injury are for people who were seriously injured by another person's negligence.
I'm not hearing you were seriously injured. I'm hearing that you were OK.
I'm also not hearing that you can prove the accident caused your lower back and abdominal pains. I am hearing that you were pregnant. Lots of things can cause lower back and abdominal pains during pregnancy. Even tougher to sort out what caused those pains a year later. So I'm hearing real proof problems.
You can find out from your insurer whether you have med pay coverage. However, if you have health insurance already and your health insurance covered your medical expenses, there's no reason to revisit it.
So, leave this incident where it is: in the past. I see no benefit for you in pursuing it.
