chart look normal at all?

This is my first month diligently charting and I feel like it all looks a little wonky. So far I've had 0 pms symptoms and I'm usually so sore in the chest that I could scream. DH and I did travel during my fertile week and came home 2 days ago. His parents' house is always freezing. Could this affect anything? Do my little hearts look appropriately timed? Basically anyone with bbt experience want to weigh in? 

Sorry for being incredibly needy.
