Literally just was forced to the hospital for a "critically low BMI." I've NEVER had a regular cycle in my life--the closest to it I ever got was getting 4 periods in 3 months like every 15-30 days (nothing the 4 years before that and nothing the 6 months after that).

But the last three months I've had bleeding towards the end of the month every month? I don't know if it's heavy enough to be a "period" (before when I menstruated it'd be like soak a super plus tampon AND pad in like four hours, now I just wear a pair of period underwear, maybe a light or regular tampon at the heaviest of times that lasts 5-6 hours. It only lasts like 3-4 days too, not anywhere from 5 to 16 days like before.

Idk, I know one of the old criteria they got rid of for anorexia was amenorrhea, but this is kinda the opposite where I get "dangerously underweight" (only according to my psychiatrist, not the MDs at l'hopital) and for the second time in 15 years post menarche have three months of something resembling a regular cycle?

Anyone have any kind of explanation?
