7 days late!! Big fat negative

Jessica • Mon, Feb 22

So AF still hadn't shown and I keep getting negative test. We didn't baby dance that much so I'm not surprised. But what does this mean did I even ovulate this month? My fertile window according to this app is this weekend? Is that true if I haven't even had a period? My cycle is 30-31 days and had been for 7 months now I'm on cycle day 38?!? Any suggestions?
