I'm so sorry for your loss
I've had 2 ectopic pregnancies. My first was in my L tube which was removed back in June 05, and then the second was only three months later in September 05, and that was cornual (in the stump of what remained of the tube).
I have gone on to have two beautiful children in May 07 and Dec 08. Your single tube will now move from month to month from L to R ovary. My daughter was conceived with my R tube with an egg from my L ovary - absolutely amazing!
Best wishes. The pain does get easier, but the loss will always be raw. You will get through it though, I promise.
Here is my thread about my ectopic pregnancies - I hope it helps
PS - I found out that mine was due to an undiagnosed case of chlamydia. It causes PID (Pelvic Inflammatory Disease) that causes scarring to the tubes. Its a silent disease and I have absolutely no idea how long I had it for. It was treated with 2 tablets. Thats it. Please see your dr and ask for a test for chlamydia. I have no idea why it isn't mandatory for testing for chlamydia after an ectopic pregnancy, especially since over 50% of ectopics are due to chlamydia. Take care xx
