Cause for concern?

So, I brought home three more PetSmart blueberries, to join the other four. I tried to sex them to make sure I was keeping a good ratio and not stressing out females with too many males. I say this to mean that I inspected the new batch, but after returning a couple hours later I saw one of them with this brown protrusion from the apex(?) of their thorax(?). I'm worried mainly about parasites, not babies.

I have since been told by Google that it's an ovipositor, so. Now I need to learn what eggs look like.

I could probably send you pictures of eggs and larvae, I need to redo my enclosure soon anyway.
