Is my BBT chart looking good? Need advices please!

Emilie • Mom of a baby girl born November 4th 2016 after ttc 18 months. Baby #2 due Sept 19 2018 :) 💕💕💕 I'm a french canadian 🇨🇦 so sorry if my english sounds a bit crappy sometimes. I'm trying my best !

I know its in Celsius but i want to know if its looking good or not.

Ps. Forgot to close to window last night so today's drop might be because of it.
