LOSING HOPE.

So I'm 12dpo and I took a test and it's negative. But my period is 7 days late. Yes, I ovulate extremely late apparently.. idk if this is a regular thing because this is my first month taking opks. But my cycles have NEVER been more than 32 days. They're always 29-32 days long. But I'm currently on cycle day 37. Any opinions on if they think I'm pregnant or not? I took the test at 4:00pm because I figured 12dpo was long enough but maybe it's too early? Or I need to just take it in the morning? I'm losing hope that I'm pregnant. I hated seeing that damn BFN. Any opinions?
