Going on vaca!

Ashley
Hey gals. I'm going on vacation the 22nd through the 24th. My period is "supposed" to come the 20th, but it's all over the place all the time. Please help me either push it off or make it come earlier so I can enjoy my vacation with my boyfriend. I am currently using no birth control & that's not an option but I'm open to anything else. Please help!!!! Thanks 😊
