Weddding and honeymoon.

So I just started my period the 24th of this month and my period usually last for about 5-6 days. I am getting married on September 7 and my tracker is showing that I have a 22% chance of getting pregnant that day and my last day of ovulating being the 8th. My question is am I gonna be okay to have sex during our honeymoon which will be the 9-15 without having to worry about a big chance of getting pregnant? I can’t use birth control or plan B because of a health issue I have. We are planning on using condoms but just in case they break I just wanna know my odds.
