Confused!

Kendra

<a href="https://play.google.com/store/apps/details?id=com.glow.android">Glow app</a> shows I am 14DPO and AF due today. Another app shows I am 6DPO based on BBT. Thoughts? I have done OPKs and had what I thought was a positive on 2/23 and then based on CM and another OPK I think it was actually 3/3 or 3/4. I seriously need some help.
