Can I sue my hospital for misleading information?

I found out that I was pregnant in July of 2010. My last period was june 16th...When I didnt get my monthly I went and got a pregnancy test and it came out positive. In August ended up getting rushed to the hospital because I had ped out when I got there the doctor did a blood test and insisted that I was not pregnant even after we had told him about the test and my missed periods. He didnt even bother doing a ultrasound ust to be sure he insisted the test are never wrong and they released me from the hospital with myself being under the impression that I wasnt pregnant. In Sep. I still had not had my monthly and I was getting really sick so I took another pregnancy test that showed that I was pregnant I took the test with me to a different hospital and they did the blood test and ultrasound and told me I was 13wks and 5 days pregnant. but a couple weeks after that appointment I ended up having a miscarriage. It just so happens that the hospital that ade the mistake was the same hospital I had trouble with when I was pregnant with my son, and many other people have said they ad problems with the hospital. I'm just wanting to know if I can sue the hospital or doctor for the misleading information that he gave me in the first place. Cause were thinking I had been pregnant at the time I went to that hospital and when I had ped out they didnt even bother to check if I was pregnant and if my baby was ok. If anyone could please help me it would be very much appreciated.
