medical negligence?

Tw tramatic birth
Sorry this is long
I'm wanting to know if I should take this further.

I had my 3rd child this year. When we arrived at the hospital, my waters had broken and I was having contactions 4 minutes apart. The midwife was very blase, didn't check how many cms I was, just stated that I didn't look like I was in active labour yet and I should go home. I asked to stay a little longer to see how things progress, which she said was fine, but she wouldn't be calling my private Dr as she didn't want to wake him until she really had to.

In less than 30 minutes I was pushing, it was too late for pain relief and when they called my dr he was unavailable.
In the birth suite the midwife said the babies heart rate was dropping so they called in a public dr. Bub was born not crying but they said it was fine.
The dr left as he was needed elsewhere.
I was haemorrhaging and falling in amd out of consciousness. The midwives where pushing on my stomach and the pain was unbelievable. The Dr popped back in to see how we were doing, be immediately took over. I was given lots of medication to stop the bleeding, the dr left again and the midwife cleaned me up but seemed in a rush to get me out of the birthing suite and into the care of different nurses when I clearly wasn't ok yet.

My partner looked after bub and I met the baby the next morning. I was still bleeding alot and very weak but was also running on the new mum emotion.
I left hospital but returned a few days later via ambulance in extreme pain, i couldn't walk or talk, only scream. I had sharp pains in my stomach and losing quite a bit of blood. At the hospital a junior dr was about to run tests to see what was wrong. But then a senior Dr took over, said it was just after birth pains (made me feel like I was being very dramatic) I felt very silly. The pain continued.
In this time I also seen two gps, one said it was nothing time wouldn't handle and the other said gallstones.

A few days after I heard and felt a big pop sound in my stomach, instantly my vision went blurry, I was in extreme pain, I could hardly walk. I went back to the hospital and got the original student Dr who diagnosed me with retained placenta, a bad uti and mastitis. I was extremely sick. I had to have a d&c, 4 days of iv antibiotics. My baby spent most of that time in the nursery. The d&c so had was so rough I was still in pain 5 weeks after and have a permanent sore small bruise on my stomach. The midwife that was there when I gave birth came and told me the monitor had moved and wasn't picking up my babies heart rate but mine instead. This has left me feeling sick that he wasn't properly monitored and is there a reason why he didn't cry after being born?

I've suffered terrible postpartum depression, I had trouble bonding with my baby. I have no faith in the medical system. I feel really let down, I felt scared. Family had to take lots of time off work which hurt financially.
It's taken me a long time to recover and I'm in a good place with my baby now but I feel like I need closure, I lay awake for hours at night and replay it all in my head.

My family have urged me to take this further. Do you think it's worth it or is this a common occurrence? Has anyone taken this to a lawyer? What steps should I take next?
