I need opinions, please! Look at my chart!

Natalie • I'm a 32 year old wife and mother of one.

I'm really hoping I'm pregnant but I can't tell what's going on here! Because of my job, sometimes I have to take my temperature early/late. I know that can cause somewhat inaccurate temperatures. Even I saw it tending down I thought for sure that my period was on its way. I'm supposed to start tomorrow but my temperature shot back up today.

The solid dots mean the temp was taken around the consistent time. The hollow dots mean early/late temp.
