I've known a couple of women who have used Ovulex who got pregnant, and I'm assuming that it was that that helped...but I can't be sure. Sorry.
I'm so sorry that you're discouraged by your results, but I am GLAD that you are getting answers and that your doc is "getting the ball rolling", so to speak. The dye test has sometimes seemed to work to clear any blockages you may have DURING the test, so it's not a bad one to have, I think. Still, perhaps while you're waiting for that you can ask the specialist for other options in the meantime.
I do so hope that you get answers. It sounds like your doc is willing to go in different directions for you to try to get you that BFP. I hope that the appointment today goes well! Please update us!!!
