So, my period hasn’t come for about 60 days now

Patient: So, my period hasn’t come for about 60 days now.. don’t crave for food, haven’t been eating at all or anything sour. My breasts don’t hurt. Pain in lower stomach, feels like theirs gas but I haven’t been passing gas. I’m a habitual weed smoker, I literally smoke all day, everyday. Would this make my period come irregularly? I’m worried I’m pregnant.

Symptoms: Loss in appetite
don’t need to urinate often
no period for 60 days
lower back pain
stomach feels bloated
