The cup?

Ka

So I’m wanting to get the cup but wanting to know if it’d be worth it. I’ve got the implant in my arm so my periods are a little weird now. I get it for about a week very light to where it won’t fill up a tampon any or none will be on pad but there’s blood when I wipe. Then a week will go by and I’ll have another one. So would it be worth it to get one even if I don’t have a lot of blood coming out? This may sound dumb but will it even catch it?
