Period Abnormalities

A

so this isn’t my problem but it’s my bffs.

ever since 5th grade (15 yrs now) she’s had a really irregular period. i mean REALLY irregular.

She has her period all day everyday, for the whole month. With only 2-4 days of break and then she’s on it again. It’s been like this ever since she’s started her period for the first time.

She’s tried Birth control (many types) and it hasn’t worked. She’s tried natural pills and it worked for a bit but her body adjusted and it stopped working for her. Not to mention her period is SUPER heavy. She bleeds through Ultra tampons in 30 minutes. Depending on the day it can be worse.

she’s been to so many doctors but no one has given her answers and i was just wondering if any of you may have answers?
