Conflicting O-dates

I have been using Fertility Friend and Glow since July and tracking BBT since about mid-August. Last week Glow changed my fertile week and O-date but no changes in FF. AF was due yesterday but still hasn't come. I haven't had my usual cramps or the PMS I'm used to. I have posted both charts. 
Do you think I ovulated CD14 or CD21? 
If CD14 should I take a HPT
Any help/ thoughts/suggestions are appreciated! Thanks ladies ?
Also looking for a cycle buddy!
