Yes! I had to have my cervix tied with both of my pregnancies because I have a shortened cervix. My pregnancy with my DD was perfect--nothing wrong except a little case of gestational diabetes (which was very controllable).
My DS--I have to take insulin shots, got an infection from the cervix operation, he had cysts in his brain, I coudln't sleep, couldn't concentrate, got a scare for trisomy 18, his HR would fluxuate out of control, yeast infections galore, U/S every week, monitor his HR every week, he had to spend a week in the hospital etc. I'm sure there is more, but I try not to think about it. :)
Hang in there. I have found that through the difficulty with my little man, he turned out to be the biggest sweetheart there is :) Although, he was very difficult the first year of his life (colicky, horrible sleep patters, wouldn't eat but get constipated).
Anyway, once you're past all of that--it is worth it. All I did was concentrate on the day. I couldn't control much, but just tried to concentrate on the moment. I know how you are feeling and it really stinks but there is a rainbow after the cloud, I promise! My little guy is a happy and health almost two year old.
