Could I have had my baby early because of my car accident? Should I sue?

I was in a car accident at 32 weeks pregnant. I started having contractions the very next day. I went to the dr and they told me it was just Braxton Hicks. I went back to work for one more week and the contractions just kept getting worse so my dr took me out and put me on bed rest. I then had my baby 3 weeks later (at 36 weeks). I delivered her normally, but the midwife who delivered me said that my placenta was very damaged, and she asked if I smoked. I told her no and that I was in a car accident and she said that could be why it was so damaged. Is it possible that I had my baby 4 weeks premature because of the accident? Would I have a case if I got a lawyer? I could really use the money to pay for all of our medical bills.
