First Step to becoming a Mommy

Well, we had out inital consultation with our doc and after listening to everything I am torn. As he listed off the tests to be done most will be on me. He listed things and all were issues as to why I can't keep a baby is because of something wrong with my insides not by husbands. So now part of me is worried that when we have the answer it will actually be something that my body didn't do or didn't produce and I am the reason I lost our children. I never thought of that as part of all of this. I wanted the answer so much I didn't think about how I would be able to handle that news.
They took all my history and all my husband's and then immediately began testing. They took about 30 viles of my blood to run every single test under the sun on it which is good. They also assign me a nurse that is my case manager so if I ever have a concern or question I can call her directly and she knows my case and everything about me.  The next part is that I have to schedule an appointment for the third day of my menstral cycle where they run a bunch of tests that day. They explained everything and what they are looking for which is good. The place also has support groups and people to talk to aside from your doctor about everything you are going through which is nice.
I am nervous as to what they are gong to find. I just can't wait to be a mom and carry the baby inside of me and experience all that. I am very anxious about all of it.
