BBT, CM, charting... Oh my

Alexa
I am excited but some what overwhelmed! I haven't been consistent with my BBT, but I had many days of a temp at 96.81-96.86. I didn't temp around when I ovulated though. After ovulation, (I am now 7 dpo, my temp has been consistently at 97.31-97.5 for about four days. What should I think about this? I had two days of major headache and back pain which was my first pregnancy sign.. Along with cramping. I am trying SO hard not to test but I'm considering it already!
