Help!

So last month, I took plan b (4-21) and I got my period on 5-5. A couple days before I was suppose to get period but hey, I got. Well, my period is due on 6-3 and my boobs have been hurting so bad. Could this be because of the extra hormones from plan b that I took from last month..? I know that plan b messes up your body with the extra hormones but I was just curious to see if this has happened to anyone else😩
