im 16 and started going through puberty when i was about 10 but i havent had many 'real' periods, perhaps 3. otherwise im fully developed and you really wouldnt be able to tell but i know it worries my mum aswell as me. i get extremely light periods not worth a proper pad all day i think they are monthly but im not certain. also i have to wear a thin pad every day due to excess mucus production. can anyone help explain this?
