Am I?

I know my roommate is pregnant and she has symptoms all her own. I have recently started having symptoms but they are the complete opposite. She’s always tired and can sleep, I can’t sleep. She’s not really hungry, I’m always hungry. She craves sweets, I crave spicy. The only thing I have that she doesn’t is severe acid reflux when laying down and mild cramping here and there at least 2 times a day. (Feels like I’m being pinched from the inside of my uterus.) Help my test was negative and I’m two weeks just under two weeks away from my period.
