Hey KG2022,
Like everyone, I'm so sorry for your loss, and importantly, this is a loss. Don't minimise it because it was early, or because not that many people knew you were pregnant - I went through something similar and one of my biggest regrets was keeping it to myself and minimising my feelings so as not to make anyone feel uncomfortable.
Allow yourself some time to grieve, and also acknowledge that there isn't anything you could have done. I found it useful to listen to some of the "Worst Girl Gang Ever" podcast episodes, just to hear about other people's experiences and kind of normalise where I was at. It also just allowed me to find some time to empathise and identify with other people and have a good cry in my car if I felt I wanted to, with no judgement from anyone else.
You can't solve your heartbreak with any one thing, but talking to people certainly helps, especially your family and other half. It also made me suddenly realise that a lot of people have gone through this, or something like this, and allowed me to lean on them when I needed to. Also now latterly, it has allowed me to support other friends who have felt comfortable talking to me when they have had a miscarriage, or similar problems, and so we have found comfort in each other, and I hope in some way, I've been able to help them too. There are of course organisation like Tommys which can offer you counselling, and should definitely be considered if you feel your grief is turning into something more serious or you want specific coping strategies for your situation.
Take some time from work if you can - don't work like a martyr if you don't have to. As I said, this is real grief, and you should give yourself some time to process. I resented everyone who expected me to be "normal" in the few months afterwards, even if I hadn't told them what had happened, which was unfair on my part, because they can't read minds and know what I was going through. You will find your new normal eventually, and be aware that the hormones do hang around and leave you vulnerable for a few months.
I also went down the surgical route - it felt like the the most "certain" option and I was in and out of hospital in a day with no complications. This is totally your choice, don't let anyone pressure you to go one way or the other and pick what your gut tells you is the best option.
And don't give up hope - no one expects this to happen to them or to be their story, but here we are. I am expecting our baby girl to arrive in March, and going through what I went through made me realise that I was ready to become a mum despite how terrified I am!
Big love, I'll be thinking of you.
