Confused!

Lee • Mommy to 3 year old girl! Baby #2 joining us March 2016!!!
If it seems like my temp should be on it's way up, it goes down! If my temp does go up, my cervical mucus isn't the right kind! If Glow says my AF should be coming, she shows early or late! I feel like my reproductive system is checking this app and always doing the opposite! Does anyone else feel like their body is super confusing?
