Late period, negative pregnancy result

Megan
I'm only 2 days late, but for me hate kinda weird. I've taken so many tests all say negative. My husband says I just need to wait that it's probably too early for a positive. Could I still be pregnant or is it something else. I've had cramps, some nausea, and use taken more naps this week than I have in a long time. (course that could be from my husbands snoring) I hope I'm pregnant, but this is different for me.
