Wantababy - I’m so sorry to hear about what you’re going through. I don’t have a success story to share, but based on everything I’ve read on this thread, I don’t think you should give up. At the very least, get a second opinion.
First of all, I have never heard of someone being told they would miscarry every time they got pregnant! Yes, your risks are higher due to the PCOS and that you’re not getting any younger, but there are tons of 38 year old + women on these boards who have PCOS and have had healthy pregnancies. I would post your question on the PCOS thread to get the best response/advice. I hadn’t heard that endo increases your risk of miscarriage, but I really don’t know anything about it, and I’m not sure what the diabetes would do to cause you to miscarry. I would think it would be more a risk to you than the baby, but again I don’t know much about it. In any case, make sure you understand why your Dr. thinks that these three things in combo will result in loss every time.
Do you know why you had the 3 losses? For eg did you have any chromosome tests done on the babies? Have you had recurrent pregnancy loss testing to rule out clotting and auto immune issues? There may be something you could do improve your chances next time around.
Also, (assuming money’s not stopping you), it may be worth it to do IVF yourself. That way at least they can see how your eggs are looking, fertilizing and dividing, and put the best embryos back in. Of course, it doesn’t prevent you from having miscarriage again, but at least can give you better picture of what’s going on inside your body and help you decide if it’s worth it to keep trying.
Good luck, I hope you find some better answers.
