Feeling so down...

This is my first time posting here so I will give you all a little background.  My husband is 30 and I am 31.  We have been TTC #2 for 13 months.  Back in October I went to my OBGYN, and had a bunch of testing done including a HSG...everything came back normal.  My husband had a SA done and came back with low morphology.  Well this month I started spotting 8 days before my period was due.  This was a first for me so I thought maybe it was implantation.  Nope I spotted for 3 days and then full blown period.  I have never had such a short cycle in my life.  Now I am worried there might be something wrong with me.  Just so tired of month after month being disappointed.  I am trying to stay positive but it is getting so hard...on to month #14 =(
