Hi, Brandi!
That is exactly what my temps looked like when I first started charting. Sometimes that first cycle goes wonky just to mess with your head!
But yes, you could O ... it doesn't look like you have yet, but if you get a nice temperature rise the next several days, FF might mark it at CD 12 or so.
Look through the chart gallery there on FF and I promise there will be lots that look kind of the same. If you want to see those specifically, click Chart Gallery up at the top and then Find Charts Like Yours. Uncheck the O Day box and check Pre-O Temps instead, then search. At least a few should come up and you can see what they ended up doing.
Temp fluctuations are always normal, don't worry. As you get further along the chart will expand and trust me, they won't look as crazy anymore.
