BBT chart expert please!!!

So I just started using bbt chart this month to help us know when I will be ovulated, as per our OB’s recommendation also.

So below is my updated chart. Based on it I am now at 11 DPO. I only felt some cramps at the left part of my pelvic, sore breast and felt like my menstruation will start so soon. By the way based on this app, I will have my menstruation on January 8. So If it doesn’t come I’m planning to take test the day after.

But based on this one, can somebody knew if I should have high hopes for it?

BTW, I just had chemical pregnancy last month. 😢 So I don’t know how to feel this time. 😞
