I'm not sure if you have or want to try birth control but I'm using the depo shot and haven't had a period in a few months. Also the side affects never really affected me. I hope you find something that helps!
Goody or bc powders are the only thing that work for me. I have a condition not going to go into the details of it but it makes my period feel somebody's carving my insides with a butter knife lol so yea I feel you
