I've had my nexplanon for a little more than a month , I got my first period on June 7th, and after I got brown spotting on and off throughout the month. This month I got very bloated and gassy, I thought it was my period, but I just got more brown discharge , is this normal? I haven't been sexually active since June 14 ish, I don't think I'm pregnant I just think something is wrong with me .
