Does having blocked tubes mean you are more susceptible to ectopic pregnancies? Or will unblocking your tubes put you in a position of being normal (or normal with PCOS)?

If there is an option for unblocking your tubes which would mean that you are no more or less likely to have and ectopic pregnancy, then i would chose that option. Do you have a great rapport with your FS? Do you think if s/he said do option A or do B then you will be swayed by their answer? Personally i am incredibly annoyed for you that you wasted so much time and energy and emotion into clomid, FSH etc when, lets face it, with blocked tubes it was never going to work. That's not fair on you!

Is your sole reason for wanting IVF because you are scared of ectopics? DO you have other reasons i.e. sick of waiting, resigned to the fact you'll need it anyway etc? IVF can be a wonderful and fulfilling thing. It also presents problems and scenarios that normal conceptions simple never stumble on.
