"i have been on nexplanon for almost 3 months. i have had one normal period (3 to 7 days). i got on my period again almost 2 months ago and i am still on! i am not used to this at all. before this medicine, my periods only last a maximum of 4 days! it has been on almost 2 months now! i am buying tampons after tampons and it definitely horrible if you are in a relationship! to be honest that and a little bit of weight gain are my only side effects (and the weight issue i&#039;m ok with because i am a slender woman) but this period issue is just too much and if it wasn&#039;t for that issue, i would love this birth control but i can&#039;t do this to my body! all this heavy bleeding! i just can&#039;t do it anymore. so unfortunately i am going to get it taken out."
