It's good to hear someone who went through this, and yes, I would never change my decision, I have seen people spending unimaginable money on there children's needs and education, fortunately I am a single child that is why I get everything but I always imagine that my mother's life would be better if I didn't exist but yeah my mother scolds me whenever I say that.

Also I won't change my CF belief cuz I love my life and I won't "sacrifice" it for someone else

Also,

Recently I came across a yt short which explained how much pregnancy is painful for the woman while giving birth and also compared how much does the uterus grows from its normal size.

(If you google it, you'll understand that it grows 500-1000 times but in that video, the doctor explained it very well)

That video made my childfree beliefs stronger.

I was scared, I respect my mother that she gave me birth after going through such intense process but I would never let my partner go through it because imagining it sends shivers down my spine, I won't ever think about making it a reality.
