Hi. I recently had my baby June 20th of this year (2015) and haven't had a period since, except for the 3 weeks after she was born until Sunday, September 27th and I'm still menstruating today. Is this normal? By the way I got the Implanon birth control

Your hormones are. in flux, with both estrogen and progesterone being regulated by your body to get back to normal cycle. With the Implanon then you have a definite amounts of progestin into your bloodstream, therefore you did not have periods. The menstrual flow right now could mean that your body is low on progestin for whatever reason. Call your GYN or family physician to see what they have to suggest.
