FF Open Circles

Can anyone tell me how to manually insert an open circle on Fertility Friend? My hubby is a volunteer firefighter and got a fire call that woke me up around 3:45AM. I fell back asleep and still took my temp at 5AM as always but I am aware that being awake for even a short period of time may have affected things. Incidentally, my temp today was the exact same as yesterdays. So I don't know if it could be correct or not. Thanks for your advice ladies!
