Because I was switched to a different birthcontrol pill. I took the ec pill while on my period last this month my period was screwed I got brownish red not the normal period as I normally have. Last week I saw my bf and we had sex and he didn't used a condom the next day which was last Friday I took another ec pill because I got scared that my period won't come because I never got brownish red period. I'm on the first week of birth control pills this week and last night I noticed pinkish and a little bit of red on the paper only one time. Could that be fromantic the emergency pill? Last month I took an emergency pill and also this month.
