30 day cycle, early or late ovulation?

Emmacool

Based on bbt chart, I ovulated on cd11, in a 30 day cycle. Didn't get my peak OPK, but almost.

After CD15 my opks dropped to no line so i didnt log them.

I didn't do any opks CD18-CD25.

CD26 Ive gotten a faint opk.

Is it possible I didn't ovulate CD11 and my body making a second attempt to ovulate CD18-CD26?

Husband has just had surgery so we can't BD anyway, but I'm just looking to understand my cycle better for next time.
