Can I sue for wrong diagnosis leading to miscarriage?

Hi. It is very hurting that I had a miscarriage which could have been prevented if the doctor had diagnosed it correctly. I was 6 weeks pregnant as of 22nd May. I found very slight blood spotting on 22nd may late evening. On 23rd early morning i called the hospital emergency, explained my situation as the spotting increased a bit. Being Saturday, the On Call doctor called me and said, it looks like UTI, and doctor advised me to go to a nearest laboratory and get a test. As advised i had gone and gave a urine sample. After few hours, the doctor at the laboratory had come and congratulated us and said it was just a UTI and prescribed antibiotics. I called my friends who is an OB GYN and he immediately said it was wrongly diagnosed. He said it was not the case of UTI but Threatened abortion. He asked me to take Ecospirin and Progesterone. However the doctor at the lab said, its just UTI and said, the spotting should go away. However the spotting only increased. on 26th (Tuesday) morning, got a call from the hospital asking me to stop taking the antibiotics immediately and she should visit the hospital to get a blood test done. I had gone and gave blood sample on 26th and they asked me to come again on 28th to check if there was an increase in HCG. By that time, the blood loss was too much and i got cramps as well. On 28th morning they prescribed me progesterone. I knew very well that it was way too late and this morning got a call stating it was a miscarriage. I can say very confidently that it was a wrong diagnosis which led to my abortion. I am new to the country so not sure how to sue the hospital for the wrong diagnosis. Any help is much appreciated.
