so I was supposed to start my period yesterday 9/13/16. when I do start it's normally when I wake up. there wasn't any sign of it coming, so I took a test. (I know I shouldn't take one that soon) and it was negative. now I still haven't started, and I'm hoping it was just too soon to test. I normally get my period early or right on time. we've been ttc for about 15 months now. I'm so ready to be a mom!! please pray I get my bfp soon :) Thanks!!
