new to this?

i just started taking the pill a couple months ago. I take it everyday at 10am but today i completely forgot till about 9pm. this is the second week the first day. i've read lots of this that if you take the combination pill and you still take it during 24 hours you're fine, if you're past the first week. but i would be 2nd week first day.. should i be okay or use backup method?
