If you type recurrent miscarriage into google it will come up with lots of sites - I have read them all!
I have 2 living children from my first marriage, no problems concieving, pregnancy or births. With no 2 dh we had three early miscarriages (8, 6 and 12 weeks) and then fell pg with identical twin girls. Unfortunately we lost our girls at 22 weeks due to iugr and ttts. Since then I have had 5 further miscarriages (8 5 5 9 and 9 weeks). I am under the care of a recurrent miscarriage specialist. We have had very nearly every test going but we keep coming up fine. No one person in the medical profession has been able to tell us why and therefore that we cannot. Our girls made it past the early miscarriage threat but weost them to specific I'd twin problem. Although we list them they are our only hope that we can actually manage it together iyswim.
I think a vast majority of women never get an answer - and that is ver distressing. You will be checked for blood problems, thyroid problems, hormone problems, nk cells ( very expensive and only available privately), uterus problems and cervix problems and diabetes. Ooh and chromosome abnormalities and your oh will have a sperm test. If nothing comes up o. Any of these tests you may fall into the no answers category.
We are stll trying and hoping one day we WILL bring home a baby.
It takes a lot of emotional strength to keep going after miscarriage but the only alternative is to give up trying.
I hope you get some answers and that you have more luck next time.
