Would you take this malpractice case if misdiagnosis led to premature labor?

I was 5 months pregnant when I called my OB because I was having severe stomach pain, nausea and vomiting. I was advised to go to the ER where I was treated for dehydration and sent home (OB never came to see me). Next day, I followed up at OB's office where I was told I had a stomach bug and advised to rest for a few days. Three days later, I was back in the ER because pain had not subsided and I had lost 10 lbs from not being able to eat or drink all week. After exam, OB still thought I had a stomach bug and treated me for dehydration. That afternoon, baby was born - 15 weeks early. Next day, OB wanted to send me home, still convinced I had a bug. It wasn't until the following day, when pain still had not subsided and I still couldn't eat/drink, that he ordered an MRI. Turns out my appendix had ruptured. Baby died and I spent a total of 8 days in the hospital. OB told me later he thought premature labor was caused by the infection from the ruptured appendix.
