I got the Nexplanon birth implant in the beginning of July. On the 17th of July, I went to the toilet and saw some brown discharge in my pants, just like spotting, which what I presumed it was. However this lasted 2 weeks, with some days being a tiny bit of blood, and some days nothing at all. After the 2 weeks, it stopped, leaving me with 2 weeks of no discharge, however my normal vaginal discharge was very heavy. Then the 17th of August, today, I have found brown discharge again, with a bit of blood. Now is this a period? As it has happened on the same day the next month. Do I just have prolonged periods, which is just brown discharge? Thanks in advance.
