Hi guys! So about a month ago I took plan B it was two days after my period ended and my boyfriend accidentally came inside when the condom slipped off. I'm on birth control but this month they switched it and I forgot to take the very first day pill on time so we panicked and I took plan B. Looking back I was probably okay and just put a shit ton of hormones in my body but I'd rather be safe than sorry. Today I was suppose to start m new period and it hasn't came. I know plan B can make your period late but earlier this week I had some light brownish red discharge while I went to the bathroom I assumed this was my period about to come but it has stopped since and now I have nothing. When should I be concerned if I don't get my period and does it sound like I am probably freaking out over nothing?
