If my doctor misdiagnosed my ectopic pregnancy what are my rights?

I found out I was pregnant in Feb. and a few days afterwards went to the ER because I had mild cramping and bleeding. Had an ultrasound that showed no bath but my uterus walls were thick. I told them from my limp I should be 8 weeks and a baby would be visible they agreed and did an internal ultrasound still no baby. Well I had my hcg beta quant levels read and they were 5, 000 still low for someone who should be 2months I was told to follow up with my own dr which I did my labs were redrawn and the dr started telling me it looks like I’m having a miscarriage that night I had bleeding again so the. Dr called me back the next day and said my numbers went up but didn’t double so she said she was going to call down to the ultrasound dept and see if they can squeeze me in. She called back and said she talked to the other dr and said an ultrasound wouldn’t stop me from having a miscarriage and told me to come in that next Monday for another test. So I had my blood drawn again and they dr talked about grieving about my loss she said she will get me on birth control and she will follow me till my hcg levels where normal the next day she left a message on my phone saying my numbers dropped and she will see me in a week for more blood work. So that following sat I was rushed to the ER in pain they got my records from the other hospital and after that its blurry I woke up in ICU with the surgeon telling me I had my right fallopian tube removed and she glad I woke up because she almost lost me because my vitals dropped low I was told the crash cart was rushed in the room. I kn. Ectopic pregnancy can happen to anyone but I’ve been complaining to my dr for over two weeks about it and it wasn’t caught or even brought up again.
