Is it bad to take multiple contraceptive pills in one dah

So I’m only 21 but I have really bad memory sometimes I will take my contraceptive pill then forget I have taken it and take another or I won’t be able to remember if I have taken it and decide to take it again just incase. One time it turned out I had taken the pill 4 times in one night because my friend had realised and called me out on it. Is this dangerous?
