Weird cycles back to back, when should it return to normal?

How long do you think it should take for my cycle to even back out? Last month my cycle was 39 days, and this month I didn't ovulate. My cycles are almost always 28 days, give or take a day. For those of you who have had a very strange cycle or two in a row, how long did it take to even back out/go back to normal.
