I have had the nexplanon for almost 9 months now. As soon as i got it put it I only got a period like every 3 months but it only lasted a few days and was mostly nasty brown blood. Well I got my period this month on Father’s day. I have not stopped bleeding since and it’s a gross thick brown blood. I’m not sure if i should be concerned or not. I know the nexplanon has a tendency of making your period crazy but I just need someone to settle my mind.
