Not sure if this is the right forum! I’m a 22 year old female and my normal weight has always been around 112 pounds. I’ve noticed this past week that I’ve lost about 5 pounds without a diet physical activity change. I also get weird menstrual cycles where I bleed lightly mid cycle for a week, but not sure if that’s related. I’m going to the doctor today, but wanted to see if anyone else has any opinion, or if I should worry about something serious.
