Anyone back to charting bbt?

I am back to charting and been having a rough time due to irregular cycles. I have attached my chart but basically it shifted yesterday showing I've ovulated already instead of next week? Also, if thats true, we had sex Tuesday and Thursday (late late night). Which of these occurances would I be concerned about getting pregnant? Sorry I sound so clueless just been so long since I've charted and understood my fertility 😊
