Help! I've been eating like crazy the last couple weeks...

The past month I've been craving all kinds of foods and just wanting to eat everything, this usually isn't like me. I'll get cravings during pms but nothing crazy. I'm on the pill, but I've been on antibiotics twice within the last two months. I doubt I'm pregnant, but could stress be causing me to eat like this? My boyfriends brother has been staying with us the past month off and on and it's driving me nuts bc I don't like people in my space like that. Just wondering if anyone has been through anything like this before and if it's stress/depression that's all of a sudden making me wanna eat everything in sight.
