Well, the pattern all checks out ok. In row 7, the number of yo and ssk equal each other so you should start the row with 152sts and end the row with 152. The repeat between the asterisks takes 19sts and is repeated 7 times. Count off the 19 stitch repeat and see if you can tell where you're using up more than 19sts.
It's frustrating but once you put in markers this all becomes easier.
