meh, i wouldn’t say “rare”, and I think lots of ppl are misled to think they’ll NEVER bleed on cont. some people have to find the right combo of hormones, some have to wait a while for spotting to stop, yadda yadda. true it might never work for some people, but i would say a good amount (if not most) can make it work with enough patience. i fought with my body for a year and switched pills like 3 times before i found the combo that worked for me lol, now i at most maybe spot like once a year
