17dpo - no af and BFN. Help please?!

Hello!! This wait is killing me. What happened to TWW?? Lol! I'm not usually late so I am so confused. This would be my 2nd AF off Mirena this year. I had it removed around same time last year and last year my cycles went on like normal...af was never late and cycles were normal 27 and 28 days. Could someone please take a look at my charts? Considering no af and bfn...I'm wondering if maybe I ovulated later than expected or not at all? I'm new to temping and it's a little confusing to me. Thanks so much!
