Missed pill

Hi so Im on Tri sprintec a combination pill, I was very religious in taking the pill at 9pm everyday until recently. 
It was 9pm on Saturday and I realised I didnt take Friday's pill; so I doubled up and took both pills at 9pm that day. 
Am I still proctected? This would mean it would have been a full 48hrs since I took my last active pill (Wed), theres so much conflicting information on the internet I am unsure. Also I was on the 3rd week of the pack if that helps. Thank you!
