Plan B

So I've taken plan B before but got over my period about a two weeks ago and had unprotected sex and got some more and now here I am this week with a period.. I freaked out for a second because this has only happened once before where I got two in one month but my Bf pointed out to me (I just wasn't listening at the time) that it does affect your cycle so it all makes sense and adds up and I'm stress relieved but like not because of this period but I guess it's what I get for doing unprotected lol. Anyone else ever go through this ?
