I'm so sorry for your loss. I know how devestating it can be. I had two children before my ectopic and so never considered the possibility.
I had pain in my tube after my MTX shot and it continued on and off for probably about six or seven months after the shot. You only would lose the tube if it ruptured or if you have surgery. With the MTX shot, there is no reason that you'd lose it.
I hope your numbers continue to drop.
