testing in the morning

Honestly I have no clue when I ovulated this month. Husband had lost his job so I wasn't really tracking well. Not sure when my period is due, I could be late for all I know. I have done nothing but cry for the last 12 hours, I've had a headache for days, I'm exhausted but can't sleep and all I can think about is my next meal, I even wake up in the middle of the night just to eat. The same symptoms as when I was pregnant before. I just asked dh to grab a pack of tests at the store and we'll see. My hopes are kind of up but at the same time not really.
