I'm sorry for your losses @Jessem1 ❤️
I was referred to infertility first as we struggled to concieve in the first year. The referral took 4 months, but I actually did conceive on cycle 16 but then had a mmc. So we continued with the pathway. I had a scan and hsg (dye in tubes) test - waited about 8 weeks for these. I concieved quickly after and had another mmc, so I was referred for a hysteroscopy (camera in uterus) under general, waited 3 months for that. At that time I was referred to the recurrent miscarriage clinic (separate from infertility) and that took 4 months but I rid get an earlier cancellation, pre-covid. They took bloods and tested for Antiphospholipid syndrome, lupus anticoagulant, thyroid, Factor V Leiden and a couple of others. The bloods take about 8 weeks to come back but my follow up appointment was 4 months later to discuss the results, which were all normal. I had a chemical pregnancy while I was waiting for my review appointment. As my investigations were normal the recurrent miscarriage clinic said I could have early scans in my next pregnancy but offered no treatment.
We were referred for ivf by the infertility clinic and that was due to start in September but I concieved after my first scan with them and had another mmc.
So we are at the point of private testing now, partly because the nhs have found nothing and I feel ivf will work in that I'll get pregnant but I will miscarry. Private testing is expensive but quick - my results were back in 2 weeks and I have a reason for my losses, aggressive nk cells, so I'm on a treatment plan now.
I hope you're not waiting too long for the recurrent tests - checking for the antiphospholipid and lupus anticoagulant is the first port of call as if you have this there is a protocol to follow. My experience with the nhs is if you don't have this, they just tell you to keep going and one day you'll get there, they hope.
Best wishes x
