Never mind I found it.
Check-Ride/Line-Check Exemption. FAR §61.56(d) states that a flight review is unnecessary if within the preceding twenty-four months a pilot has passed a pilot proficiency check conducted by an examiner, an approved pilot check airman, or a U.S. Armed Force, for a pilot certificate, rating, or operating privilege. This means that a pilot who has passed a check-ride or line-check need not accomplish a flight review for another twenty-four months following the successful completion of that check-ride or line-check.
Oh and I agree I wouldn't fly a 172 right now without an instructor atleast untill I land it a few times without incident.
And since you weren't sure what I meant by a flight review, here it is:
FAR §61.56(c) goes on to say that the flight review must have been accomplished within the twenty-four calendar months preceding the month in which a pilot acts as pilot in command in an aircraft for which that pilot is rated. The authorized instructor must also endorse the pilot’s logbook certifying that the pilot has satisfactorily completed the flight review. A pilot’s demonstration of competency in any aircraft satisfies the requirements for all other categories or classes of aircraft for which the pilot is rated.
but if you get another rating within the 2 years or participate in the Wings program you don't need a review.
