Justcurious55 and Fr_Chuck have answered this one correctly:
It was up to you to find a clinic that could give you a timely appointment.
Until you finally had your appointment, the clinic had no duty toward you. Were you previously a patient of that clinic? And, in any event, while I am not a physician, I don't see anything that suggests that the miscarriage was due to lack of prenatal care.
You are going to have to be able to prove that something could have been done on or After November 8th that would have saved the baby.
