Ohhh, implanon memang macam tu lah! A few of my mum friends pakai and most of them stop period altogether or jadi very spotty je, which is actually normal side effect. The hormone in the implant thins your uterine lining so your body produces less period blood, some girls bertuah no period at all, some still bleeding but super light lang. Best thing is to check with your doctor if you just inserted it, maybe give it a few months for your body to adjust, but if you're worried or if it's been a long time and something feels off, definitely go see them, they can confirm everything is okay with the implant placement.
