And for others it's the opposite and some women have long lasting side-effects after quitting taking the pill (unregular menstruation is a common one).

One gf I had basically stopped having periods and cramps at all and was just fine with that. She pointed out that she was always one of the lucky ones with "light symptoms" anyway.

that’s absolutely not true of all women, some can’t even take hormonal birth control at all - it’s relatively common to have problems with it, sometimes even long-term

it’s nowhere close to a solved problem, unfortunately
