No Luck

After 2 1/2yrs there's still no luck...my period has been 2 weeks late but nothing. I'm starting to become discouraged especially when I see all my friends getting pregnant or bringing their beautiful babies into the world. I tried just settling for my God babies hoping maybe it'll be enough but I still feel that void. I had my first miscarriage at 19 and now I'm 26 and still nothing. I honestly dont know what to do.
