I think you should have the lap - if there is endo in there causing the problem, IVF may not be as successful as it could be. Plus having the lap might be all you need to be able to fall pg on your own. If it were me, I would be wanting to make sure that I gave myself the best possible chance of conception if I was going to have to spend a lot of money on IVF.

Your other alternative is to see a Gyno who will do it in the public system so you wont have to pay for it, but the risk of that is being put at the mercy of the public hospital waiting lists, so you could have to wait several months before having the lap and I'm guessing you want to get started on this as soon as you can.
