ever since i got on birth control, i have my period but barely bleed it feels like im wasting products. what should i do?

You can just use liners

if you bleed very minimally you can use liners. at first i'd be careful of how much they absorb and how often you'd need to change them! but it'll be less waste and also less painful (if you use tampons it can be too dry and become painful)

Personally I haven’t used them but you could maybe try period underwear

tbh i free bleed if there’s only enough to show when i wipe and nothing ends up on the pad
