BBT Chart experts, I need your input please!

I've been charting for 3 months, TTC for 10 months after MC. This month my temps are looking worrying, I am worried that I didn't O because temps post O are not much higher than pre O. 
I was sick on CD13, thus the high temp. Got a positive OPK CD16, negative OPK ons day 17. I am going to have a progestorone test done 7DPO to confirm levels.
I would greatly appreciate any insight.
