So, I've been on the Nexplanon for about a year and 3 months, now. I have been period free up until about 3 weeks ago when I had heavy brown discharge. The next day, it stopped. A week ago I had the same thing happen to me. Light brown discharge. Next day, again it stopped. Now today, I check and once again I have light brown discharge. I haven't had my period since about a month before I got the Nexplanon. This is the first time in a year I've gotten this random brown spotting. Also, I've noticed it happens after my boyfriend and I have sex like about a day or two later. Does anyone know what's going on? Is this even normal? I get so super worried.
