Bicycling my pill?

So I have a special occasion coming up on the week I’m meant to have my withdrawal bleed and I was thinking it may be best to bicycle (take two pill strips back to back) my pills so I skip out that withdrawal bleed. Have any of you tried this? I’m just a bit nervous i don’t know why. Also after taking it for two months would I have another seven day break and then go back to taking one strip at a time or how does it work? Someone help please. (I’m on the 21 day combined pill)
