TWW is Murder

So I am only 6 DPO but the TWW is killing me. This will be my first pregnancy if we make it this month and I have no idea what to look out for 🤷🏻‍♀️. I been experiencing on and off pinpoint pinching sensations on my left side of my pelvis - what could this be? It has gone on and off the past couple of days. This is also the first chart I have experienced such a continuous rise in my bbt. Usually there is some fluctuation.

Any suggestions when I should start testing?
