VACATION TIME!!!

So next month im going on vacation!!!!! Yaaay going to miami for my 21st birthday but it seems like ill be starting my period halfway into it.. sad part is my boyfriend is going and we do long distance so i havent had sex in a while. I wanted to have sex the whole trip but now my trip has been ruined! I wont enjoy it as much because my pms and the cramping.. i wish there was a way to delay your period im so tired of this.. just take the whole uterus out lol
