Day 52 flower, some plants producing few seeds, are these feminized??

So I'm day 52 of flower and about 4 weeks ago or so a plant popped a few nanners so I killed it. Now some of my female plants are popping a few seeds. Does this mean the seeds will be female? I've read some on this and everybody seems to disagree. There has to be a right answer, is this how feminized seeds come to?

typically but they probably have a better chance of throwing nanners down the line.
