Sickness? Or something else....

Ni
So ever since I got off birth control (June 30th I think) I have been having mood swings not much of appetite ... Just crampyness (not period related) but I'm 8-9 days away from it.. but the smells of red meats turn my stomach I can't stomach my health products that I try and take. I'm neasous only at night time so now I've been drinking peppermint water.. so I guess my question is: will the side effects from getting off bc go away? Or should I go see a doctor... But I just had my ultrasound done they checked everything "down there" and everything is normal and no damage from bc so that's a good thing. My anxiety was bad yesterday evening... I'm not sure can I get some helpful advice.
