BBT & OPK charts

Jane
Hi ladies, help please 😊
 
First time monitoring bbt and taking opks.
 
Would any you mind letting me know what you think, I have added my chart and also opk taken on CD14. Do you think this was my ovulation day? 
Just unsure whether to keep taking OPKs for rest of cycle just in case it wasn't ovulation. 
I have crazy cycles from 27-44days! Xx
