The pattern doesn't give number of stitches in the next row, just purl.
Row after this is knit, then back to same pattern I gave you. 33 sts is the start of the first row again, to repeat the pattern.
Maybe the first row is wrong?
k1, *(yo, k1)twice, yo, ssk twice, sl 2sts knitwise-k1-psso, k2tog twice, (yo, k1) 3 time; rep from * to end.
Row 2 Purl
row 3 knit. Repeat this pattern rows 1-4 three times, so I would say that 33 sts is the same number throughout.
