Ovulation bbt chart help!

Melinda • Had 4 miscarriages in 2015 and had our rainbow baby December 2016
These charts completely confuse me. Can anyone please help me understand mine? Does it look like I ovulated and when? I miscarried early the end of feb and expect my cycle to be weird. My levels went to negative right away. I haven't been good this month using OPKs as we have been packing and moving. Anyone?
