(32 now) sometimes had my interval for 21 days, then 3 mos next to nothing, later 2 regular in a row merely to be followed by 2/month

Women merely please !?

this happened to me, and i enjoy a "bicornuate uterus" [By-Core-New-Ate]. Which means my uterus have two horns, or splits off contained by the middle.

i was prescribed birth control pills as a childish girl to make my length light and incentive me less PMS and mood swings.

Tell your own flesh and blood practitioner of your concerns, he/she will be able to diagnose your daughter at best!
