taking pill back to back

Hi girls I was due to stop taking my pill yesterday but have decided to take it back to back due to going away next week so I want to avoid being on my period. I usually take my pill st 11:30 and this morning I didn't take it until 13.35, shall I go back to taking the pill at my nlrmal time of 11:30 or continue this pack and take it at 13:35? I'm just conscious as I had sex with my partner last night and my birth control pill is our only method... it is microgynon pill that I'm on and I take it for 3 weeks and have a 1 week break. Any help would be appreciated!
