luteal phase 16days long?

So...quick background info:
My cycles are 30/31 days...ALWAYS. Never been shorter.
I got a +opk on cd12, think I ovulated on cd13.
When i put this into glow it moved my period 4 days sooner giving me a 27 day cycle. If I am not pregnant this month, there is NO WAY I will get my period when glow says because my cycles are NEVER that short.
This means, I have a longer luteal phase of 16days.
Will this affect when I can test for pregnancy??
