On January 24th I started what I think was my period . It lasted from the 24th - 27th . It was kinda light bleeding the 4 days but it was dark in color . I read that online implantation bleeding is a light pink color but mine was a dark red color . Also that implantation usually last a few hours but in rare cases can last 1-2 days but my period was 3-4 . I think I m just stressing myself out but do you think this was my period or implantation ?
