Arrgh! Anyone else had this before?
I'm using the ovia app to track my period, dtd, and CM. based on what I've entered its moved my fertility window twice already this month, and I've logged my info tonight and it's done it again!!
It says today is my most fertile day so that's not too bad, but I've also had two other fertile windows this month according to the app!
I'm so confused! What do I believe?
