Clomid round 2

          I am on my second round of clomid and just finished ovulating.  I was wondering what kind of symptoms other women have had on this drug.  I've experienced headaches, a couple migranes, moodiness, and some blurred vision.  I'm only doing two rounds so I'm done with the pills..... I'm hoping I finally get my BFP but I've been trying so long now that I'm just not expecting to ever get one.
          I guess I'm just looking for a little extra support.  Been TTC for 2 1/2 years and I'm in my late 20's and both my husband and I have been checked out and have been told everything's fine.... Yet we haven't been able to conceive yet.  Feeling a little down and frustrated lately.  Hubby is being retested soon and then the next step is an infertility clinic... Any success stories to give me some hope?
