Row 1: *(k2tog) 4 times, (yo, k1) 7 times, yo, (ssk) 4 times; rep from *across
Row 2 and 3: knit across
Row 4: Purl across
It shouldn't be increasing across row 1 or any of the other rows. On row one you derease 8sts (4x k2tog and 4x ssk). There are 7 yarn overs and later, one yarn over for a total of 8sts increased. So repeat the k2tog x4, the yo x7, a yo x1 and then the ssk x4 and you should be ok. See if you can go back over the last row one on the needle and identify all the sts to find out where you're gaining sts. It may also help to put in stitch markers between the repeats. These can be a simple as circles of yarn if you'd like.
