Hi, I’ve currently been on the nexplanon for about a year or longer. It stopped all my periods after a month. I recently just started getting my periods back two or three months ago. Wondering if my birth control is still working or if I should get it looked at? I’m currently very sexually active and didn’t start bleeding till I started having sex again. I’ve been constantly cramping which is a new side effect. My breast have also changed, very sensitive, tender, swollen and a dramatic change in size on one breast. Do I consult a doctor or is this normal.
