Brummie, god, I so understand that feeling that people think you should have got over it! After my last one, I really hit that brick wall, and it was so hard to find an outlet for this relentless grief.
I had some counselling and acupuncture, which helped deal with some of the effects of grief, but otherwise it was being here where it felt safe (and even then I worried that I was taking up too much of everyone's time), and lots and lots of time. I withdrew from everything, including work, which I eventually resigned from, and didn't do much socialising.
it sounds empty now, but time does heal some of the scars. it never goes away, that "otherness", but it becomes easier to bare and feels less raw. It is still very early for you, and your grief is very natural.
The Coventry protocol is progesterone from 7 days post ov, which is continued until 12 weeks if pg, or stopped after BFN, and heparin from scan showing sac in the right place until 12 weeks. If you are diagnosed with high NK cells, prednisolone from BFP to 12 weeks.
I believe the uterine scratch is also beneficial as it encourages lining growth.
I hope your appointment goes well, when you have it.
