Sirdar 9634 pattern help please

[Kirbym]

Hi, having not done any knitting for over ten years I think I chose a pattern that is confusing me on the first row.
Can anyone answer this question. If it says p3(inc in next st,k1) twice, inc in next st,p3(ytb,s1,yft) 2 times how many stitches should I have on my needle?

I have written it exactly as it is written on the pattern, any help gratefully received. By the way, I am a uk member, are there many of us on the forum?

Thanks xx
