Autoimmune disease

Misty
Tomorrow is the day my husband and I have been anxiously awaiting for months. After suffering two consecutive miscarriages and one before our daughter we are to start testing for autoimmune dieases and or disorders. With each lost pregnancy, we had D&C's and testing done on the babies. There were no choromsonal defects and since I was able to carry one healthy baby almost to full term (we were induced early due to preeclampsia)  the shape and orientation of my uterus isn't the issue ( although I do have an anterverted uterus). I am just really nervous about what the doctors will say and how indepth this journey will be. I'm mad we have to do this. I'm sad my husband has to once again be strong and hold my hand through yet another struggle. I just want to be strong for him and for our daughter. I hate this. You never want to hear something is wrong with you but I almost want them to tell me yes this is what you have so we can deal with it and move forward. I just don't know what I will do if they tell me there is nothing they can do. I don't know if I can ever allow myself to become pregnant again if they tell me there is nothing they can do to help ensure I will carry the baby into a third trimester. I'm scared either way. I never thought finding out I have a disease would be the better of two options. Has anyone else gone through this? I don't know anyone else personally who has been diagnosed and have no one to talk to. I do have a wonderful support system of family and friends but of course all of them had no miscarriages and definitely did not have 3. I feel so alone sometimes. As much as they want to help there is nothing to say and nothing anyone can do. If anyone else has had to go through testing pleas share your story.
