I don't know much about endo. But my FS said to have the lap first before we did anything so we could see what was happening inside. He said there wasn't much point of you didn't know whether your tubes were blocked or if there was scar tissue impacting on fertility. So we did that even before trying clomid or anything.

If you don't tryst your FS it's good to see someone else, and it sounds like the mixed stories she gives is reason to get a second opinion.

Worth asking the Gp if there are any public services that can help.
