So usually when I bleed I’m light red. I’ve got the Nexplanon birth control the implant that goes in your arm. I’ve bled for about 4 months straight off & on. Then stopped for awhile. Then I started to bleed dark brown. I thought this was my period but when I bleed I usually bleed light red. I did start to have sex after I stopped bleeding & Im curious can someone please help me explain if this is normal to bleed dark brown??
