on the mini pill bleeding is especially weird i think, my guess is because there’s no proper break or dedicated time to flush stuff out, so it’s a little bit that lasts a long time. i’ve noticed since switching to a mini pill, even though mine is slynd and it has a placebo week, my bleeding never lines up with the inactive pills, and it’s light and lasts longer than it did on the combined pill. sometimes it’s more heavy and ends quicker, but when it’s really light I find it takes much longer to end.
