What colour is implantation bleeding ?

Implantation bleedin: Typically this is pinkish to red.

Spotting: Despite the folk lore implantation bleeding is not common and if it happens it is more of a spotting than a "bleed" If you miss your period by 4-5 days, do a home pregnancy test. If the result is negative repeat the test 4-5 days later unless you get a period by then. Use first morning urine and follow the instructions for the test carefully.
