Yeah people react differently and it could take a little while for your body to get used to it, ive had implanon for nearly 4 months and i dont get periods but i do get little bits of brown spotting every now and then and some uterine cramping...not sure why it happens but i guess its to do with the hormones making my uterus baby resistent.
Everyone is different so it might settle down but if not then you can always get it removed.
hey, i have been on implanon for a little over 2 months now. at first i had sore breast, then when i started bleeding(for a month straight) they werent sore. now that i'm not bleeding they are sore again, going on 2 1/2 weeks long of sore breast...oh and i tend to get nauseated ALOT!! ..i think its just some of the possible side effects though
