help me figure out when to test!!

[CapitalChick]

If FF lists my expected period date at Feb 19th, what's the absolute earliest I should test with a first response??

I would think maybe the 16th? or the 15th? I could be wrong, so hopefully someone else will be along shortly in case I am lol...good luck testing this month!
