hi, i couldnt help but notice, that what you have said sounds a lot liek what i go threw with my periods and some obgyn visets, has your doctor ever talked to you about Endometriosis . or checked for it, im 25 i got my period when i was 9 and was dx with it when i was 14. its reked havic, caused cysts painfull sex, painfull obgyn visutes, evon caused an abnormal papsmer.
Endometriosis can lead to cansor, but if you have endo, and a good doc, for the most part it dosnt get that far, if treated, its not a 100% garentee that if u have endo u get cansor, but it dose put you at a higher risk.
when i reall started compaling about t he pain and the messed up perioeds and a bunch of other stuff my obgyn figuard it was jsut becuse i was young, finaly at 14 she concluded that, endo was what i had, now it wasnt till i was 21 years old before they went in and did what i call a fishing expadition, surgey to 100% conferm it. endo for me has caused lots of issues, back pain (ontop of messed up b ack) migrains irregluar periods, not being able to have children becuse mine is so bad and ive had it for so long, abnormal papsmersh. if u havent talekd to ur doc about Endometriosis , pls do. i hope this helped some.
