Hi! I have been on Nexplanon since 11/07/2011. I haven t had any periods since then. However yesterday I had a brown discharge (not a lot). Today when I went to the toilet I saw only when I was wiping that I had a little but of brown/dark red discharge, but no spots on my underwear. I am very concerned, so I would appreciate any advise. I don t know if that is relevant but I was under a lot of stress lately and I was also taking Clindamycin antibiotic since I had a very bad cold. Thanks, Yana
Hello, I would be happy to help you with your question. Stress can have an effect on cycles and cause irregular bleeding, but this is unlikely to be a factor in this case in the setting of the birth control that you are on.  Clindamycin has no effect on its effectiveness either and is likely not the cause of the abnormal bleeding. The bleeding is likely just "breakthrough" bleeding related to thinning of the uterine lining that occurs while you are on birth control.  Make sure you check a pregnancy test and wait and see if it goes away for now. I hope that this helps and good luck!
