Complain?

The lead up and birth of my son is something over the past couple weeks I have been struggling to deal with and I am unsure wether to go through with a formal complaint or not.

So at 36 weeks I started to feel unwell and had a constant headache that just wouldn’t shift. I seen my midwife and she had said she would like me to go to the hospital to be monitored. I went there on the first day and because my blood pressure wasn’t as high the told me to go home so I did. The next day I felt worse than before and I had more intense swelling than what I had previously, my eyelids were so swollen it was hard to open my eyes. I went back to the hospital when they again told me to go home, this time telling me that my headache was a tension headache and that my high blood pressure was caused due to stress. I went home only to go back again the next day when one doctor decided to put me on medication to control the high blood pressure and made an appointment for the midwife to see me at home because traveling obviously stressed me out and caused the high blood pressure. The midwife saw me at the house the next day and my blood pressure was the highest that it’s ever been and I have now developed tremors in my hands and visual disturbances. She recommended I go back to the hospital which I did and they then decided to keep me over night at which point the shakes had now gone to my legs at which point the consultant had told me that she would like to start to induce me at 37 w and 2 days. When I moved to the labor suite to get my waters broken they recommended an epidural so that they could control my blood pressure whilst in labor, I had the hormone infusion to start my contractions and I had one and my sons heart rate dropped and wouldn’t pick back up. With that I was rushed to theatre where he was born via c section within minutes. I was then told that my placenta had started to come away and was told that I had preeclampsia and not a tension headache like they told me at the start. My son then developed jaundice having been born early and started phototherapy. In the night I had noticed he looked unwell and was clammy. I called for a midwife and she had taken the fan I was using to keep him cool away and told me he was fine, when I tried to tell her he was unwell and rolling his eyes into the back of this head, she dismissed me once more. I asked another midwife in the morning and she had seen him rolling his eyes and spoke to the paediatric team who took him away to the special care baby unit and started him on two antibiotics to combat sepsis.

My question is should I raise a complaint about my experience because in my eyes this could have been a near miss causing the life of my son. They failed to spot the pre eclampsia having come to them 4 separate times and they wouldn’t take me on when I had said I was concerned about my sons wellbeing. Would you complain if you were me?
