Sayang, this is something you really need to check with your doctor or clinic asap, okay? Implant contraception boleh affect your period in different ways, tapi missed periods especially 2 bulan jadi kena confirm either way, better safe than sorry! One of my mum friends had the same thing and turned out it was just hormonal adjustment, tapi she still went to check. Please go see your GP or go back to the clinic where you got your implant, they can do a quick test and give you proper advice based on your situation. Don't worry la, but jangan delay okay?
