Need help understand beginning of pattern

[eadunphy]

Hi - I'm new here and so glad to find you all! I am about to begin a project but I am stuck on understanding the initial instructions. The pattern says:

Cast on 12sts. (start with a K row) I understand casting on but not "start with a K row) then it goes on to:

Row

1 Inc 1 st at each end of row (14sts)

2 P across

How do I get to 14 sts at the end of Row 1 when its my first row after casting on 12 sts - shouldn't this end with 13sts? Am I supposed to knit a 2 rows for the first row?

Thanks for any help
