Sooooo.....Ovia predicted my "fertility window" to be the 3rd thru the 6th and my projected period to start the 18th. After editing my data (my period is always a week later than they predict because I have a longer cycle) it changed my fertility window to what is currently green. AF SHOULD be arriving tomorrow but Ovia also wants me to test tomorrow. Should I spend the money and take the test or just wait and see what happens. After my next period, I will start using OPKs and temping consistently as of the other day. I am just curious as to what your opinions are. Im not having any symptoms whatsoever. Not pregnancy or AF.
