So.... After I gave birth to my beautiful little girl, I decided to get on the birth control Implanon. Well it had been a year to the month since I had it put it my arm. I stopped having a period this entire year. Well... now I had a period last week that lasted 3 days (which has always been my normal menstration time.. 3-4days a month) & all of the sudden it decided to come back yesterday... I am just wondering if this is going to continue the entire time I am on the implanon. Cause lord I can deal with a monthly period... but not a weekly period. LOL any advice I would greatly appreciate! I am thinking of contacting my ob/gyn tomorrow b/c he will probably have better information for me considering I am his patient & he knows more about my history..
Thank you for your question and I will try to help. Breakthrough bleeding with the implantable progesterone birth control devices is extremely common.  This commonly occurs early on after their insertion.  It also occurs over time because the progesterone in the implant leads to thinning of the uterine lining (which is normal).  This thinning is associated with breakthrough bleeding.  I do not think that this is your period because you cannot physiologically get a period every two weeks.  Finally, make sure that you check a pregnancy test.  I agree that contacting your OB/GUN is a great idea. I hope that this helps and good luck!
