medical malpractice?

I found out I was pregnant on Nov. I had an ultrasound found in uterus. I returned for follow up after 2 days. I had an ultrasound again. She told me that is a ectopic pregnancy. I was shocked and asked the doctor why I was told the baby is in uterus two days ago. She said the body absorbed it and gave me two options only with methotrexate or surgery. I asked she had no bleeding or any pain, if I can wait for couple days and double check. but doctor said my hormone levels (HCG level) is very high. She can't wait. After a long discussion with doctor, I choose to trust her. She gave a shot with methotrexate and told me that will take 4 to 6 weeks for the pregnancy to be absorbed. Also told me come back after 4 days to have another shot. But I got a call from clinic next day and told me my HCG level was too high. Methotrexate will not work. I must have a surgical. So, she remove my fallopian tube. But the report shows no evidence of ectopic pregnancy in the entirely submitted fallopian tube. I returned to doctor office for follow up on two weeks later .The doctor said everything was fine, I was doing well. Told me to start with birth control pill and come back after 4 weeks. I got a called from doctor next day again. Told me my HCG levels still high. I had an ultrasound found a yolk sac 6 mm in size and a crown-rump length. But after that the baby never growing. Also, I never seen Dr after that day. Even I request to see her and told them I have couple questions to ask her.But the answer is she was too busy. So, I talk to the supervisor ask him if we can set up an time to talk to her . He said ok and told me come back next week. but she didn't show up. So I believe that was misdiagnoses because she didn’t check the my HCG level before treat with methotrexate. I tried to find a medical malpractice attorney. But they all said i have very difficult situation. Told me to find other attorney. What can i do now?
