I was doing a crochet pattern and don't know what round I'm on!?

Go around the row slowly and try to find your last increase of rows. By that I mean comparing what you are now doing and what you have done. The difference in the rows should be different in increase somewhere, stitches,chains,dc's etc. When you find that you should be able to "read" what you have done and what the pattern book tells you to do.
