If you found 2 chances are there's a whole lot more. When you trim you will likely find the bananas on the lower part of the plant. Cookie crosses are known to be real easy to stress and herm. Definitely let it finish hopefully there won't be a ton of seeds. Like said they will all be female seeds because there is only female traits in the pollen that popped up on a female plant. I assume you talking indoors? It doesn't take much pollen to reap havoc in an inclosed area with fans blowing it around. The most common cause of this is a light leak in the dark cycle. But there are many things that can cause stress to cause herming. Like I said cookie strains and crosses are not the easiest to grow because of that very reason. Good luck
