You're so welcome.
I'd finish the ws row and then start my increases on the next row. It really isn't that important, though, since you're doing increases on both sides, anyway.
I'm going to answer your next question before you even ask it.
How do I cast on at the beginning of a row?
Technically, you're increasing at the end of the previous row to count for the beginning of this row. You have to cast them on and work across them to get to the sleeve, then cast on at the end again.
