I need all of your birth control advice!

So I'm getting married Nov 18 and started birth control July of this year. For that month of July my period came as scheduled, the last week of the month when I started taking my brown or placebo pill. 

For August I took my pills normally around the same time everyday and my period came one day before the pack said it was due, so one day before I took the brown placebo pill. 

For September I took my pills normally around the same time everyday but my period came on the Wednesday before it was due (so 4 days before the pack said it was due, before I took the brown placebo pills). 

Here's where it gets confusing so sorry if I confuse you all! Because I didn't want to have my period when I'm on my honeymoon in November, in September when I was supposed to take the placebo pills I just started into the October pack to push my period up a week. 

So now it's October, and I was supposed to get my period on Sunday, but I haven't gotten it yet. So I guess my question is, is this normal? Does your period get all cray when you first start birth control? My period has literally never been on time, it's always been a few days early or a few days late. Also, my fiancé and I have been having sex and I know that there's always a chance that I could get pregnant even though I'm on the pill. I'm just wondering what you all think, and also hoping it comes today so I don't have it on my honeymoon 😂
