I don't know what this means....

so we have been TTC for 8 months now... I'm getting excited/nervous/I don't know.... so I am supposed to start my period on Tuesday. I usually start my period the day before or a day after, so that's not what I am nervous about. What I am nervous about is that now my breast hurt.they never hurt before when I was about to start my period. U don't want to read too much into it. I definitely don't want to get my hopes up but it's on my mind. I don't know what to thunk or do.. I'm excited cuz they never hurt before when I was going to start my period or even when I was on my period. I will keep my fingers crossed. baby dust to all of us!!! make this our month!!!! Please God!!!
