Hi, i am a 19 year old and i have recently noticed a small lump on (what i think is) my cervix. i have also noticed it has growna bit in the past few days. Also, i have gone from having very vegular periods to not really having them and evey now and then i will have brown discharge. I went to the doctors about my lack of periods and as i am on the implant that put it down to that. i have been on this for almost 3 years and feel like it shouln't effect my periods this much this late on (i would understand if it was when i firt got it put in or a few months later but not 2.5 years after) i have also had STD checks and they have come back negative and i'm starting to worry a little bit. would anybody be able to suggest what to do. or if anyone has had similar problems and what they did and what caused it.
