Which row on cables

Doing some basic cables. Put the project down and forgot about it for too long. How do I figure out which row I’m on with the cables crossing? Not sure when to cross. Uh-oh. But there must be a way to tell.

Most of time you can spot the stitch that was pulled a bit and lengthened when the cable was crossed on the next row. You can use that to count rows and tell you when to cross next.
