Since October of last year I have been on Nexplanol. It's now the end of February and I have experienced extended periods between this time, which I believe is it's my body adjusting to it? But since it's been almost half a year, is it normal to still be bleeding for almost a month at a time? Are there any health concerns up should be paying attention to? I sometimes notice it is light, but always there. Sometimes when cleaning myself, I notice blobs of blood, but not often.
