3 period on the pill?

Julia • 25 💁🏼‍♀️ Trying to live my best life

I am in the middle of taking my placebo pills with 2 left to take and it looks like my period is drawing to a close already. Usually I finish my period when I get to the yellow pills and take at least one of them. Has this happened to anyone else? Is this normal? Thanks in advance :)
