Hi @tallla
I'm so sorry to hear your this, and wishing you lots of strength. 
My baby boy was diagnosed with a chromosome abnormality Oct 18 through combined screening and CVS, we also decided to let him go at 14 weeks.
I opted for medical management, a very personal choice, and there is absolutely no right or wrong way of dealing with such an awful time. I chose to see my son after I delivered him, my partner did not, and although I took photos, my partner still hasn't chosen to see him over a year on - and I feel that is ok and his choice. He finds it hard in his own way and I accept that we are emotionally different.
The lead up to delivery was very distressing, but somehow my mind just clicked during the procedure and it was quite peaceful in the end. Baby was handed over to me in a quiet room, in a tiny Moses basket provided by the ward, and had a blanket etc. I did take my own bits for him too, like his little teddy and own blanket, which I had a square cut off to keep with him, and I have kept the rest of it in his memory box. We then decided on a private burial near home, and also named him. It gives me somewhere to go and see him, I guess I can still take care of him even though he physically isn't with me. I think I took the whole ordeal very hard, as he was my first child which took us 3.5yrs to conceive. I still struggle from time to time.
I had 6 weeks off work, I felt I needed longer, but my sick leave ran out and couldn't afford any more time off. My job didn't help in the fact that it was focused on disabled young people and adults. My partner had four weeks off but equally struggled as much.
My sick note stated "pregnancy complications" which annoyed me, as to me it was a bereavement and should've been treated that way. Everyone was really supportive once they knew though, fortunately. If you can, take as long as you need to in order to cope.
I didn't talk to my immediately family during the lead up to medical management or for two weeks after. This was because I could not cope with them being as emotionally distraught as me, but everyone's families are different so I hope you have lots of good support around you.
Recently the first anniversary passed and I coped quite well really, ups and downs throughout the year, varying emotions and sadness, but I don't feel any regret as I knew my son would be bound to a lifetime of pain and struggle, and I was terrified that given our fertility issues, he would likely not have had any siblings and no one would be around to make sure he was okay when we were no longer on this earth, or worse, he quite likely would've died quite early on in life.
Sorry for rambling.. You must do what you feel is right for you, ultimately. Everyone's choices are different and as I say, there is no wrong or right way. Most importantly, take good care of yourselves during this really sad time. Lots of love to you.
