So sorry for your loss.
I got pregnant the first time in my 30's too, after 4yrs TTC. I paid for the NIPT and unfortunately, the foetus had patau syndrome and we lost him at 12 weeks.
I then lost 2 more at 7 and 9 weeks. The last was after IVF and I'd seen a heartbeat only a week earlier. Further IVF rounds and no further pregnancies.
The way I got through, was thinking about the positives of my situation. I realise this sounds odd, but it helped me. Your positives will be different. Some of mine were:
-I lived in a country with generally, safe healthcare, access to ultrasounds and antibiotics if needed
-I had, and still do have a loving and supportive husband
-I was able to access IVF years later after further years of TTC (despite no actual cause for sub-fertility ever found).
-I was grateful that my losses were early on- before I was showing and before people would have asked more questions. I was glad I wasn't close to term or having a still birth
-I had good health and no reason to suspect I'd never conceive again
You might want to have a memory box- scan photos, 1st positive pregnancy test etc. Sometimes it helps to have a little ceremony. Write a letter to your baby, light a candle and say some words, plant a special tree in the garden etc.
I don't have any living children, but to have 3 losses is uncommon. Majority do have successful pregnancies after a loss.
Remember that you aren't alone Ami5 and this is not your fault.
The miscarriage society have some great info to help, plus a phone helpline. I'm also happy to answer any questions you might have x

Edit- forgot to say. You can TTC again once all bleeding has stopped for at least 2 days apparently. I've been on mumsnet years, and there are cases where someone has TTC straight away- before getting a period after the loss and did get pregnant. It does seem though, that many of these pregnancies end in MC once again. Not all, there are some successes, but I do think the uterus needs to completely clear and then build a thick lining again. Personally, I waited for at least 1 period post the loss, before TTC again.
