Need help quick, pregnant neon tetra?

[cheeesymelon]

1 neon seemed to be "bullying" the other tetras (or so I thought) , she wanted to just stay by her self and when others came near she would chase them off! I don't know if she just wants to "sleep" or something but I need to know if she's pregnant ergently because I want the fry to survive! You can't see properly in the pictures but she definitely has a big belly!
Thanks
