Ladies, I need your advice/opinions

I'm a month late, I have fairly mild cramping, ive been hungry like no other, I can't take a basket of laundry up a flight of stairs which out being winded by the time I reach the top, I feel really bloated, and my sex drive has been way down..... I've taken two tests. One was expired and the other was just bought both were negative. But that doesn't explain the way I've been feeling and being a month late. What do y'all think I should do?
