Suing the NHS?

I’m just wondering if anyone has tried to sue the NHS and been successful? I had an ectopic pregnancy back in July this year and ended up having my right fallopian tube removed. I feel the nhs were completely negligent towards me. To give some back story, I found out I was pregnant on the 17th June. On the 24th of June I booked a GP appointment as I was spotting and having lower back pain. I have endometriosis and PCOS so knew I was at risk of having an ectopic pregnancy and was very worried. On the 25th of June I ended up having severe stomach pain (to the point I was on the floor crying) I called 111 and went to a&e where I was told that my pregnancy test was negative (it was very faint positive I have photos) & I must be having a miscarriage. I told him my concerns about it potentially being an ectopic pregnancy and he completely dismissed them. I asked him to do blood tests or send me for a scan or absolutely anything and told him I had been to the GP the day before and tested positive at the doctors surgery. He was completely dismissive and told me I could test again in a few days but if I was pregnant he was sure I was having a miscarriage. I then ended up back in hospital on the 27th June where they did blood tests and a scan, could see fluid in my stomach but couldn’t see where it was coming from. I was sent home and booked in for bloods on the 29th June where I was told my HGC levels hadn’t risen in the way they should. They was supposed to book me in for a scan on the 1st of July but they didn’t. I managed to get a scan on the 2nd July where they then ended up rushing me into emergency theatre due to the fallopian tube rupturing and how much fluid was in my stomach. Across that week I rang 999 on 3 separate occasions, crying & begging for them to send help. 3 times they refused. Me feeling they were negligent towards me stems from my first visit at the a&e department. Had he taken my bloods like I asked him too he would’ve seen my HGC levels, they could’ve monitored them and then maybe I wouldn’t have ended up with a ruptured fallopian tube. So yeah my question is firstly am I wrong for feeling this way? Do I stand grounds?And secondly if anyone has sued the NHS how did you go about it?
