I am on Nexaplanon, i have brown discharge and after intercourse I either bleed like I am on my period or have dark discharge for days after, is this normal? I have been on it for about a year and a half and have irregular periods. I practice safe sex and use condoms as well, so I do not believe there is any chance of pregnancy. However, my breasts have been tender since engaging in intercourse, which we have been having about 4 times a week all within a short span of time, should i be concerned abojt yhe nexaplanon?
