If I have implantion bleeding when can I take a test? I'm not sure if I'm pregnant but I think I had implation bleeding but I'm not sure I had really light bleeding it wasn't enough to be on a pad it was only when I wiped none on the pad and none in the toilet just on the toilet paper and it was really light red.... So Idk if it was implantation bleeding or not... I'm new to this the bleeding stoped after a few hours...
