My joints hurts, having mood swings, tired, having strange cravings, but my period is due in a week

Pregnant or paranoid? Soo Ive been super worried I'm pregnant. I got a period last month but it was super light and just off from my normal period. I've been super ache (but its cold so idk if that's why?) My lower/ mid back, hips, knees have been hurting really bad. When I have sex or push to hard when I'm pooping it will hurt my back/ hips. Ive been feeling nauseous for on and off for the last two weeks (but I did get sick four days ago but everyone I know who got it is feeling better) Im a heavy drinker but the last two times I've gotten drunk I've had SEVERE hangovers where I throw up in the morning (which has only happen once in yhe past yr and a half of heavy drinking) usually marijuana makes my stomach problems go away but not lately. I toss and turn at night and keep my bf up.I've been having bad mood swings and want to cry a lot when something makes me to happy? Lol (I'm under lot of tress tho so idk? I have been getting tired more and going out less. Certain foods make me feel sick. I put onions on everything but not in the last two weeks. (But i was sick * had two bad bad hangovers) No change in breast. My period should be coming in the next week but I'm just super paranoid/: I don't want to take a pregnancy test yet but id like some feedback to ease my mind. Please & thank you :) .
