Af late!

I predicted my period to come last friday. Glow predicted yesterday. Today no sign... still not getting my hopes up as i read so many times ppl are a few days late and still get disappointed. I have terrible back pain and headaches. I dont normally have back pain with pms but i think my body playing tricks. Hopefully she wont show and i will test at end of week. Im excited for the possibility but scared of more disappointment after a year of ttc
