I have had nexplanon for 3 1/2 years now... Which means I just got my 2nd one implanted about 6 months ago.Now the first time I got it implanted I did not have any periods up until the last 6 months of having it in which is just due to the levels reducing and needing it replaced... but anyways here I am right now with a period and actively bleeding 6 months after getting it replaced... Don't know how long it will last or if it was a one time deal but that kinda threw me off ... any explanation??? Side not any birth control I am on I loose my period didn't have periods for 4 years on the depo shot... I just find this one sooo random???
