Here is my chart for reference :

As you can see, FF had marked with crosshairs that I O'd on CD19. I had a positive OPK the day before. However as you can see, there is no defined temp rise after O. I got one slightly higher temp than before O and 2 temps below the coverline. I am only 7DPO.
Is it unlikely that I O'd? Is there no chance I am currently pregnant?
