Birth control and periods

norma

My <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> says I am one day from ovulating. I go on vacation starting the 30th and do not want to have my period while on vacation. I have a doctor's appointment Thursday, regular check up. Anyway I read about a pill that would stop it for a few days while taking it then I saw it was not legal in the US. If I ask for birth control on Thursday is there a way I can keep from getting my period or delaying it by a week? I understand it's not healthy but I have been going thru alot and just wanna enjoy my vacation as much as possible. Or is there anything else they can give me? I am currently not on birth control btw.
