I've noticed i've been feeling bloated. it might have to do with my birth control pills. i've been taking them for about a year & never had problems.

Constipated?: Round or hard stools or straining when you poop? Constipation is the number 1 reason for abdominal pain and bloating in girls your age.

Not likely: If you have been taking the same birth control pills for a year with no problems, they are not likely to be the cause of your new feeling of bloating. Consider other causes and see your doctor if it becomes concerning.
