My story is not the same as yours, but I will share it anyway and maybe it will bring a smile to you.
My husband and I always said we would have 2 children, after we had our 2 daughters, he went to the doctor to schedule a vacetomy. We were told that our insurance would only cover it if he was 30 years old, had 3 kids or waited one year. So, he was soon to be 30 so we planned it for then. Days before he was set to go in, guess what??? I was sick, a sick I had been before, twice. I was so certain that I never even took a test, I just knew. I was upset, briefly. We couldn't afford her, would we have enough time for her, but that soon changed. I figured it was meant to be. Like any child, she is wonderful. I absolutly cannot imagine my life without her. She is beautiful, funny, smart, and my baby. She was the greatest surprise. She was a true gift I never knew I wanted, but thank God eveyday that I have her. I am sure that if you are pregnant, that it is meant to be.
By the way, the vacetomy was easy on me!

, but also pretty easy on hubby. He was nervous of course, but went to work that afternoon, I drove him, but othr then that he was fine. Best wishes to your family, I am hoping all goes well for you....
