So...for the last 6 months my period had been coming on around the 20ish of each month. I recently went to the fertility doctor because I’ve had some issues with the past with PCOS. The ran test and everything looked good. I had to take provera because I was not ovulating. Ever since I did that it pushed my period back and now my period has been coming on around the time my wedding 😩😩 I cant be on my period during my honeymoon 🤦🏽‍♀️🤦🏽‍♀️😩😩....I’m not currently on bc

Is there anyway to manipulate my cycle?!! My wedding is in March...Please help
