No menstrual cycle..

Okay so i haven’t had a period since 96 days ago..

i was on birth control a year ago for only 5 months. After that it took my period 8/9 months to show up. After that i had 2 normal cycles. Then all of a sudden i bleed for 2 months straight! The doctors said they didn’t know what was wrong and that it wasn’t hemorrhaging.. thank God! But since that i haven’t had a period! Any tips on how i can get my period back and what you think i may be going through.. THANKS❤️
