Hello, So I’m having a really weird period cycle right now.... 4 days ago I took plan b just to be 100% that my boyfriends precum would not get me pregnant. Yesterday I got blackish stuff on my underwear, it started from brown and now is black... although when I whip its blood? I also have been having mild cramps and lower back painIts confusing me if I’m having my period SUPER early or its implantation I don’t know? Here is a photo TMI WARNING BLOOD. Could ya girls or boys with better knowledge help a girl out!
