So I didn’t take my placebo pills last month and am just now ending my period after skipping the last one. It was verryy light and all the blood was brown. Is there a reason it would be that light? Should I be worried?

The pill can lighten your bleeds, it’s normal for that to happen. Brown blood is just old blood.

Birth control is known to lighten or even stop bleeding for some people. Brown is just old oxidized blood. As long as you have taken all of your pills on time within the allowed time frame and accounted for severe diarrhea or vomiting or any other interactions you are fine and protected. What you are experiencing is completely normal and you have nothing to worry about
