I have no idea if this option is feasible with a possible ectopic, but given your certainty that this is not a viable pregnancy, is RU486 a possibility? It's something I'd ask a doctor as I dont know what happens with it when a pregnancy is not in the uterus or whether any further damage to the tube could result.

i do know that general advice for an ectopic in a damaged tube is to remove the tube, in case necrosis sets in and causes other damage to the body. With my ectopic at 5 weeks, there was already necrosis.
I would assume RU486 wouldn't be an option. Ive certainly never seen it used in an ectopic pregnancy. I can only hope the pregnancy isn't in my tube. The consultant said it could very well be in the abdomen as when I had it checked years ago it was very much opened it was its ability to move which would cause a problem. So he thought there was a good chance it didn't even make it into the tube to start with. Or maybe in the other side which is also quiet possible. Either way I don't see the sense in waiting to find out.
