Okay so I took plan b 2 times in about a week or so and it has now been 4ish days since the last pill and I am experiencing brown discharge. I didnt think anything of it at first (actually I was very excited because that is how my period usually starts and ends so I thought I was just finally getting my period.) The brown discharge only lasted about a tampon and a half and then nothing after that, so is that in place of my period or could I still be pregnant or what?
