Yes, you will be fine. If that was your only miss, no back up contraception is necessary.
It does get confusing. For future reference, Planned Parenthood has a nice chart and they recommend the following...
If you miss the first one to two pills at the beginning of the pack, then you should take a pill as soon as you remember and take the next pill at the usual time. If this happens you will need a seven-day backup method of birth control.
If you miss one to two pills from day three through day 21 of your pack, then take a pill as soon as you remember and take the next pill at the usual time. If this happens, Planned Parenthood reports you do not need a backup method of birth control.
If you miss three or more pills in the first two weeks of the pack, take a pill as soon as you remember and take the next pill at the usual time. Seven-day backup birth control will be necessary in this situation.
If you miss three or more pills in the third week of the pack, do not finish the pack and throw it away. Start a new pack and use seven-day backup birth control.
Best of luck!
