OK, Contestant, I think I’m getting the picture a little better. It is a uteran pregnancy, following a clamp procedure. And the same doctor who did the first procedure is confirming the pregnancy, right?
If I may offer some advice–perhaps if you gently, delicately, but ultimately firmly discuss this with the MD and establish that there is reponsibility here, you may not have to go the length of a nasty, and probably difficult, lawsuit. Get him/her to accept the fact that the procedure, while perhaps not his/her fault, did not work and that the expenses entailing thereto should be covered by them. It might work. He/she will argue that they did their best and “things happen” but you can argue that while no guarantee was given, any “pinhole” is still the responsibility of the practitioner (while ever-so-gently suggesting that a lawsuit “could” (jurors being so vindictive) establish liability).
It is a difficult thing to argue and I suggest a lawyers advice on how to go about it (keep searching til you find one who will accept this approach–many really are greedy bastards who just want to sue, but there are also many who just want to help). Close reasoning and a nonthreatening approach can do wonders, and avoid many upset stomachs and headaches.
