FF temping...

Destiny
So I started having some light creamy brown spotting and of course went to google. My period isn't due until Tuesday/Wednesday. While looking I read that you should use the FAM setting on FF... in currently using the Advanced..... 
What do you ladies use?! I switched it over to see what would happen and it changed my ovulation date to way later and now saying I'm only 5dpo?! I don't know which to use or believe now.... (I attached my charts 1st one is Advanced 2nd FAM)
Also anyone else experience spotting this early and still get a positive?
