If I'm reading you right you aren't talking about the jog like Marria is mentioning. If you have several rows of the second color with the wrong side facing that is not the jog issue. Perhaps you were interrupted and picked your work up and pushed the whole thing inside out and started knitting. You can do that and it would do what you say. Could that be it? If you later got back to what you started with you may have done it again.
