Sending you all the love OP 
Feeling fucking livid is perfectly natural and healthy, let it out. I’m miraculously pregnant on my 6th go, no reason ever found despite all the tests available but the cocktail of meds is working and I’ll never know why.
What’s kept me going is the support I’ve had on here, there’s a ttc after multiple losses thread which made me feel less alone and gave me a safe place to rant and rave. One of the women there had several mcs because her DH had a translocation and they were told the same thing - just keep trying - which is such a pile of utter shite and so difficult mentally, but it’s also true.
Like I said, we had no reason for our losses so it’s been adding drugs in and hoping I’d keep conceiving so we’d get enough chances to try the next thing. It’s the most soul destroying, exhausting thing I’ve ever been through. The year when I didn’t conceive after catching 3 times in a row was a special kind of hell. I was sure I’d used up all my “luck” and that was that.
My DH has children from his previous marriage and as much as I knew how much he wanted a family with me, I can’t tell you how many times at 3am I’d lie awake wondering why I was putting us both through it, putting him through it when he already has perfect, healthy, beautiful children and didn’t need anymore. But I believe him when he says he never doubted we were right to carry on. We started the journey together and didn’t see how we could give up on the idea so we just kept going. You’re not doing anything TO him and he’s in it with you going through the same hope and heartbreak. You’ll be dealing with it differently and that’s natural and okay. I had huge amounts of rage towards the babies I felt kept abandoning me, he didn’t get that at all but it’s where I was for a while. He hated seeing me going through it all physically and was really traumatised by that, while I didn’t really think about it that much because it was just an unavoidable part of it all. Try and keep talking to each other. And get the help and support you need. There are, sadly, a lot of amazing posters on here who can relate and who are going through their own versions of it and can empathise with you. And professional help is there for exactly this, to give you the space to grieve and fear and rage as much as you need to.
My heart goes out to you so much.
