"i have only had nexplanon for about 1 month and i already feel like getting it taken out. i had a cycle in november right after i had my daughter in septemeber. my cycle in november only lasted 3 days and on my last day was the day i got nexplanon in. the first of december i started spotting old blood/brown blood for 7 days then my regular period came i was happy then it last for 7 days straight ok i can handle that. so from dec 8 to dec 14 i had my cycle so for 3 days no bleeding or spotting of any kind then all of a sudden on dec 19 i started spotting brown/old blood and that is still continuing and now i&#039;m starting to get cramping with it and the blood is starting to turn a brighter red. in calling my doc today."
