I am so sorry for your losses. I know how much it hurts having been there myself. Big hug!
I have had 4 losses too, 3 very early losses like you. DH is perfect. I was later diagnosed with Endometriosis Stage 4 for which I didn't have any symptoms before. The consultant seemed to think my losses were due to the Endo because they were failing to implant. We also got a second opinion from a consultant at Lister. She advised having a range of tests done to rule out various factors like Anti Cardiolipin syndrome, ANA, MTHFR, Thyroid function, NK cells, TH1-TH2, Chromosomal Karyotyping. Your GP might be able to help with some tests. From all these tests, I found out that I had high TH1-TH2 ratios which supposedly also affect implantation and attack the embryo as a foreign body. And funnily enough can be a result of having Endometriosis. Following removal of the Endo, I got pregnant in 3 cycles, but went on to have a missed miscarriage at 11wk+2. So no success yet, but have just had my TH1-TH2 levels checked and waiting for the results.
Definitely do the Chromosomal Karyotyping blood test before you embark on ICSI.
They thought I had endo when I was younger. Extremely painful periods that had me in hospital and on tramadol but they cleared up after I had my son and now are so uneventful. I wonder if it’s related.
Yeah we want the full tests before going down that route. We get no funding because I have a son but my partner has no children.
I can't advise on the miscarriages, I just wanted to say that endometriosis is often much improved after a pregnancy. Just because you now have pain-free periods does not mean that you do not have endometriosis! You may have endometriosis which is now asymptomatic as far as the pain goes, but may be a cause for the early miscarriages.
