Can someone please read my chart? :)

Hello ladies, 
​The top chart is my bbt from last cycle and the bottom is my bbt from this cycle :) I believe I am 9/10dpo today and have a few questions ..
 
​ 1) by looking at my chart.. Does it look like I could have possibly had an implantation dip this cycle at 8 dpo? Ignore he drop below cover at 4dpo :) 
​2) can you implant as late as 8dpo? 
​3) is my chart looking good? 
​Thank you! :)
