Opinions

I had AF September 5th through 9th and have not started AF which was due the 4th, anyways glow changed my ovulation for September since I have not started AF for October so the days we BD on high fertility (31%) are only 20% now but anyway that would make my implantation date at the latest the 4th of October, so if I take test now I would be to soon to get a BFP? I have taken test and they say negative and had 3 test have faint lines but think they are Evap....give me some opinions please!!!
