Oh I can only imagine how I'll feel the day I hear the heartbeat!! I'm so glad you got your sticky bean!!
I haven't read back yet, but it sounds like you are going through a bit of a tough time (if I'm wrong maybe the story will still be an encouragement to someone). I have to share a story. It's one that's given me hope and strength ever since my friend told me what happened years ago.
My good friend and her hubby had tried for 3 years to get pregnant with nothing working. They finally got to the IVF stage, and got their sticky bean. Somewhere around the middle or end of the 2nd trimester, the doctors told her that something was wrong with the baby. He had a very rare disease and it was causing his heart to form both backwards and inside out. There were other things going wrong, but honestly it's been 7 or so years since I've heard the story and I don't remember them now. Suffice to say the doctors recommended that she abort her baby because they didn't believe that he would live through the birth let alone beyond that and even if he should manage to live through the birth, he'd never have a normal life because of this - never run or play etc.
You can probably imagine just how hard this was for my friend and her hubby to hear and what a tough tough decision they had on their hands. In the end they decided to keep the baby and hope for the best. The baby was born, alive, but had NO immune system whatsoever. So the first 2 years passed with 2-3 major surgeries and a sea of sanitizer and keeping all strangers away from the house to protect the baby from germs.
That little boy is now almost 8 years old. He looks and acts like ANY normal boy - running and playing and smart as can be! You would never know from looking at him that he had such a tough start to life. Those same doctors also told my friend that the birth of her son caused enough trauma to her that she'd never have kids again. Guess what? 2 years later they had a beautiful baby girl that wasn't planned but is very loved.
I guess my point is that doctors aren't always right. There is something in the love and closeness of a family that at times can overcome even the toughest medical issues.
