*Trigger Warning* - Late term abortion update

Firstly I'd just like to say how overwhelming it was to read all the beautiful responses I received in such a vulnerable time ❤️
We decided to not abort and continue with the pregnancy. I went into spontaneous labour at 33 weeks VBAC'd my 4pd 2oz baby boy. He was also breech and only 16 months after my first cesarean.
He was with us for two hours before he passed peacefully on his own terms and we were lucky enough to spend the next two days with him in hospital getting to know our beautiful boy.
We are both devastated but at the same time we are at peace with the decision we made.
I cannot thank you all enough for the pure and genuine support ❤️

Original post:

I have very unfortunately been put in a position where a late term abortion is the best option for our baby. I am currently 21 weeks gestation.
Originally we said that this would never be an option for us but the further along I have got in the pregnancy the more apparent all of the complications have become.
Because we said this would never be an option we never asked of the process in which this is performed. We are terrified and heart broken. We are also struggling with an emence amount of guilt.
We currently know our baby's heart has two complications called Pulmonary Atrecia (no lung valve) and VSD (ventricular septal defect). To add to that our baby has scoliosis of the spine (bend in spine), the fibular bone in both legs have not formed, feet are incorrectly attatched (bending ineards as if you were walking on your outer ankle) and six toes on each foot (not the worst thing the happen). Also, there is an issue with the penis (can't remember what it was called) that can directly relate to he absence of an anus (the anus is not viewable on ultrasound).
Also I have had a previous cesarean and was informed that at this stage in pregnancy I would be offered an induction abortion. Can this affect my scar and future pregnancies? What would be the chance of needing a cesarean for an abortion because I would like to avoid this. I was aiming for a VBAC.
I would like to know any information on late term abortions, how to manage the feelings of guilt, how many regret their decisions whichever way you chose and any other information you feel would help me?
Thankyou for reading through. I know it's long and I've kept it as short as possible. The emotions surrounding this are immeasurable and we are hurting so please be as gentle as possible.
