Need help with bbt and cm! Possible tmi

Kelsey
​So here's my chart and my question! Well, flow had my ovulation prediction to be June 29 to July 5th and I had a drop in temp as you can see. However, on July 9th I started having what felt like ovulation cramps (left side and in bum) as well as on the 10th, also had EWCM which I didn't have during my window. We weren't able to bd often due to hubby being out of town, but we did bd when I was having cramps and ewcm. Just wondering what is more accurate, or if it's possible I ovulated late.
