Calling all chart experts!

What the heck is up here?

I am using Advanced digital OPKs (that go low - high - peak fertility). My O day has ranged anywhere from CD10-CD16 the last few months I've been charting. We decided to TTC on CD7 and CD8 I went right from low to peak.. now it seems as though I may be Oing today?

Any thoughts appreciated! Thanks!
