After trying unsuccessfully for six months, my doctor suggested I try Clomid.  I was ovulating but having shorter than usual luteal phases (9-10 days).  Although "luteal phase defect" is controversial, my doc thought Clomid might do the trick.  I'm so so so excited to say that it worked on the first round!  I literally couldn't believe it--I got so used to seeing only one line.  I wanted to post my story because when I first started on Clomid, I couldn't find many stories of it actually working, so I wanted to let you know that it can happen.  Good luck to all!
