Shoegal - I had a lap done years ago when my ex husband (husband at the time) and I were diagnosed with unexplained infertility afterwards. They found nothing wrong so for me it was a big waste of time. The op itself was not too traumatic but the blue dye draining from me came as a bit of a shock and I had a lot of pain associated with stitches.

Salt - I never thought of it that way regarding the EWCM after bding. We are very active in that department so that could be causing some confusion with me as well.
