In addition to regular bloodwork, my RE did genetic testing. That is where they found answers for me. I hope you find answers.
I had 2 m/cs before I had m first son. The only thing they could find was low progesterone. There are a lot of blood tests they can do, they usually start with a day 21 progesterone test to see how well you ovulated. Maybe start there. I am sorry for your losses and good luck to you.
iv had 4 miscarraiges so i know the pain and am sorry for your loss, mine too all ended at the 6- 7 wk point only one made it to 10wks iv had every test an ob can do and eveything comes back neg. you could get a blood work up to see if anything shows up, if everything is neg. than you may never know its the most frustrating part of trying again b/c in the back of my head i wonder will it end the same as before. again im sorry for your loss and i hope you can get some answeres good luck:)
I had two this year as well and my fertility specialist ran some tests to try and figure it out. They found out I have MTHFR which means I need extra folic acid and a baby aspirin everyday. I started taking that along with prometrium (for low progesterone) and now I am 17 weeks and everything is going great so far. The best thing to do is consult a doctor so maybe they can figure it out. It may just be a simple thing they can fix like your progesterone levels. It is worth it.
have they checked your progestrone levels when you are pregnant because if they are not high enough you will miscarry, or it could be a few other things the only way to know is to see a dr and have them run some test on you
