I hate myself..

I've been ttc for almost a year with PCOS and have irregular periods. The one major thing a women is suppose to do is have a baby but it's been a year and I still haven't. Then I thought this month was going to be the cycle that I'm pregnant and now I'm having brownish bloody discharge and I think it's my period.. I'm so upset with myself.. Hopefully in the next day it won't be my period..
