I usually have a period for about a week while not on implanon but this is maybe my third period in 2 years. This one has lasted 9 days and I don't know if I need to possibly get it checked out.
Is it a real heavy flow? Forget about your normal cycle when you are on hormonal birth control. You have more to get rid of because you haven't had a period every month. So if its not alot, its ok. If you should feel its alot of bleeding it won't hurt to call your doc and check ask about it.
Irregular bleeding patterns are very common with Implanon. It begins to secrete less hormone the longer it is in so in the last year of use, you may find that you have more periods and irregular bleeding. You only need to have it checked if it is extremely heavy (like soaking a large pad or super tampon every hour or less) Your body is just reacting to the reduction in hormone levels. This doesnt mean that it isnt effective anymore though. If you replace it on time, you will have enough hormone to avoid pregnancy.
I have done a lot of research on this birth control since I got my first implant almost 6 years ago. I've also asked multiple gynecologists over the years about the missing or prolonged periods. When you're on implanon it is very common to have prolonged periods. Some of us using it don't have their periods at all and others have prolonged periods for a few months but their periods go back to normal until it is about time to have it removed at the 3 year mark. It is also common to get spotting between your periods while using Implanon. Before I got my first implant I had regular periods that were no longer than a week long, after I got my first one my periods got drastically longer. Ever since that first month my periods last 2 to 3 weeks out of the month and even spotting between those periods are a normal side effect for this birth control.
