Oh Yarawin, I'm so sorry for what you've been through til now.
Sometimes you don't realise what you want until you get a glimpse of it; it was like that for me too.
Your dh doesn't get it, maybe in part because this ache obviously wasn't there before you fell pg, and maybe also because it's not logical or practical (to him) for you to feel this intensely so soon.
He may also be a little shell-shocked.
I would take some time out from the ttc talk for the moment (you can't ttc straight away anyway), maybe go and see your doctor (you've been through something SO traumatic, you may need help to heal), and in a week or so when you're feeling more yourself and more on track bring it up again so that he knows you were serious and it wasn't just the hormones and emotions talking and that this is real for you. Everything has changed for you, you need to give him time to catch up.
Stay strong, you will get through this, and we're here for you
Hugs
