other alternatives to prevent my period on the night of my wedding?

so..I'm getting married in October 20th of this year.. I absolutely LOVE glow app..it's not only 💯% accurate with period prediction..but also great women tips!

because I'm on the pill, and been on the pill since for 15+ years..my period is very predicted, don't have history of pregnancy and everything is awesome!

turns out, because glow can only predict certain months ahead for prediction of period, the month of October was just released this month...turns out...I will be in day 3 of my period on the day of my wedding..

my period is a 5 day thing with massive cramps and heavy days..by day 3, I'd probably be medium but with the pills I tend to get overly emotional and

sluggish.

can you can give me tips to see what other alternatives are there for me? I've never had an IUD so I wouldn't even know how that works, always been on, the pill, so prefer to stay it that way.

is there a way to delay my pill to prevent it from happening? would there be a risk?

please help!

thanks 😊😊
