Is any else not happy?

Not trying to be a downer beyond no means but seeing if there is anyone else in my boat! It's embarrassing! This is a time to be happy n giddy but I'm sad, unhappy, almost depressed. Never have I felt this way before. Snapping n fighting with my bf about every little thing. We r moving back in with his mother to try n save money for a home (should be living with her by end of Apr). Stomach always hurts like a stomach ache not cramping. Not much of an appetite, everything tastes blah unless it's got a kick to it (banana peppers, spicy Garlic) but too much flavor tastes gross (BBQ sauce, baked chicken). Not craving anything. I don't want sex at all, don't even want to hear anything regarding any part of it. Sleep is finicky, work hours r 20-30 a week. Been nauseated n puky since 4 weeks... I'm trying to be happy n a occasional laugh is nice but I just don't know what's wrong. I'm 12wks 1day today.. Due Oct 2nd.
