I knew there was a possibility of my foster glider momma being pregnant when I took them in. I have been watching her, but she has been really shy...until tonight. I noticed this and got her to hold still by feeding her a giant meal worm. I have no experience with breeding or joeys.. is this what I think it is?? If so what can I expect? How long do I have before it's opp? And should I do anything right now?

My girl had similar thing and it turned out to be a inverted pouch. But in this picture it looks like it's side of the pouch opening so I'm not sure. And I have no experience of babys so I wouldn't know about that.
