Early ovulation?

Nicolene 🇿🇦

I am very new to this bbt thing. According to fertility friend I ovulated on CD9 I was still waiting for the opk's that I ordered so I do not know what to think and if I really might have ovulated that time.I received them on CD13 and the results have been VERY negative. I was also still waiting for my 2 decimal bbt thermometer so these are the best I've got. What do you think do I still have a chance?
