period help!!!

Okay lovely ladies. I need help! So I'm going to visit my boyfriend on the 28th this month. We have a long distance relationship but my period is supposed to come around the time I get there! Obviously I want to get intamate with him but I cannot do that if I'm on my period...(he's anti blood) so he won't do it when I'm on it either.. any way I can make my period come sooner or delay it?
