I've been on implanon for almost my full three years , I'm supposed to have it taken out this December... Now all through out all of my three years I've had a period but they were irregular and now this month I haven't had one at all and I'm worried I might be pregnant. I been getting this brownish discharge but no bleeding and I've been having cramps like if I'm supposed to be on my period. But as I said no blood. I've herd ppl say they had no period thn started to have one but I haven't herd it the way I'm experiencing it. Im only 18 I'm not ready for a kid please help me.
