Is there anything I can take to make my period end faster?!

It's my Boyfriends birthday on Thursday and were going out to a resort. I really want to give him birthday sex because well we haven't had it in a while but I'm on my period. I really don't want to have sex if were going to be all bloody. Not our thing . I heard certain types of tea help open up the cervix & stimulate the flow to make it end faster. Any tips?
