Menstrual Cycle

Patient: I’m 14 years old and have been getting my period for over 4 years. When starting high school I didn’t get my period for two months (understandable because of nerves and stress). Well when I got it again this October it started out light then got heavier over 3-4 days but recently my flow has been so heavy that it overflows when I use a size super tampon. Like today it had been about 3 hours when it overflowed. I’m a little worried. Is there something wrong or is that natural because my normal flow isn’t like that.

Doctor:
