Im not hungry. When i eat i feel like puking.

I still havent had my period. Still yet. Sick sometimes. I dont wanna eat but when i do i feel like puking i have to smoke weed to eat. Am i pregnant? ..im not addicted to weed lol. I just started to do it cause ive havent ate for days. My husband suggest i should try cause i havent been eating. This is my only second time smoking it. My husband is a smoker not me lol. So yeah. Even when i felt really sick he said it should help me with eating. So yeah!
