Feeling Blah

I had a MC in September and we've been TTC since with no luck.  I was supposed to get my period on Wed but it didn't come.  Nor yesterday.  So I thought maybe this is it, especially because I didn't have my regular pms symptoms.  Yesterday I started having a few cramps.  Today I have cramps and what I guess is my period.  So strange because I'm pretty regular in how my pms/period progresses every month.  On top of everything I feel like crap because I thought I might have good news for my hubby and now I don't.
