Christina,
I am so sorry for your loss

I also had a tubal pregnancy two years ago. It is such a tramatic thing to go through. I remember crying because we were loosing a baby but also because I was loosing part of my fertility.
We continued to try to conceive without assistance for over a year, but with his fertility issues and the fact that I only had one tube made this an impossibility. I bypassed the IUI route due to the increased rate of tubal pregnancies because of the time it could rob me of my fertile years and also the risk to my health.
I know it is such a hard decision, the only advice I can give you is to consider your age, the time frame that you want children, and the risk you are willing to take with your health. Not to scare you, but I was told by my doctor that tubals are VERY risky and cost thousands of women their life, yearly.
