I don't know if other women on the board have had the surgery you had. I sure somebody does answer your questions. If not, are there other forum boards specifically for women who have undergone a trachelectomy? I'm wondering if Jo's Trust would be a good place to look if nobody gets back to you here.
From what I have read, you will require a cervical stitch and more than likely bedrest. The child will also be delivered via ceasarian. A friend of one of my closest friends got pregnant after a trachelectomy, years ago, and did deliver a healthy baby boy, this way. Unfortunately, I didn't know her well enough, and my friend lost contact with her. I wish I knew where she was because I'd love to put her in contact with you, so she could tell you what to expect during pregnancy. At the time, I had never heard of that surgery, and didn't even know it was called a trachelectomy. I was just so happy her doctor had made sure she could still have a baby.
If your doctor isn't giving you helpful information, though, please don't hesitate to get a different doctor. You deserve only the best, caring doctor who wants you to have all the information you need to prepare you.
