PMS on my Wedding Day?!!!

Iris
HELP! 
I just checked my future cycles and I'm due literally the day AFTER my wedding day. I have uterine fibroids which make my cycle irregular by a few days sometimes, so I'm really worried that I'm going to start sooner than <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> projects, putting my wedding day on my heaviest, most painful day. I'm talking changing a super tampon every hour kind of heavy. Not ideal when you'll need lots of energy and you'll be wearing a WHITE dress!!! 😨
Anyone else dealt with a badly timed period on your wedding?? What did you do to avoid a dress disaster? 
I've had people tell me to adjust my birth control to shift my cycle, which I would do if I was on birth control. Unfortunately, that's not an option for me. 😞
