Yup I know how this feels I just had 15 clones herm on me in the 4th week of flower gutted and heart broken I was but sometimes as you say shit happens pick yaself up and start again :) I think you would do better cropping now and not letting the seeds get any more mature than they already are no point in keeping her going shes stopped producing thc now so yeah I would chop her soon as you can :) Best of luck still looks like a very nice plant congratulations she will still be nice just pick out the seeds and youll be sound :)
