Af wasn’t supposed to be here for 12 more days . I’m irregular but the last 2 months it has came at the beginning of the month .ive also already had my af for April . Well 3 days ago I started cramping in my lower abdomen and felt Dizzy and my boobs and back were hurting . I starting bleeding very lightly but bright red and normally my periods are dark red . The first day was light and the second day I had a little to fill a tampon then it was very light and when I wiped it was a light color . No cramps with it like a normal period . It’s day 4 and i am no longer bleeding or anything . Could this have been implantation and when should I test ?
