I assume you did a pregnancy test, always the first step. This is ususally not a problem with Clomid, so I have a hard time relating it to that. Intecourse, everyday 11 to 26 is alot for any man to maintain an adequate sample, I would make sure these are the right directions. Are you sure your tubes are open after the surgery, do you have both tubes? Finally, have your Gyn do a good exam to check for other sources of bleeding, cervical infection, UTI, etc.
Hope this helps,
