Hopefully this is my lucky month!

I have 3 apps that track my period...2 say I should have started already in the past few days but glow says I have 5 days left....About 5 days ago I had cramps so bad they woke me up from sleep...Not to mention I never get cramps, even on my period...Today glow sent me a little notification to do a breast exam on myself and they feel more full and round...I'm a 32A so I definitely knew the difference no soreness just bigger looking lol. I hope these things mean something & I'm not tricking myself....We've been ttc since Oct 2013 but only 1 month with glow. Send prayers!
