Ma-tsu shed on the 28th of January after multiple Neptune shaggings since late November. I let her be since then, set up the nesting box, and have waited. She's acting very much like her usual self since she shed, cruising, and for the life of me I can't tell if she's actually gravid or not. I think she is, but I second guess it as my imagination. I've tried feeling for follicles, but again I can't really tell what's going on.

Is it possible that I'm crazy and she's not gravid? After how long should I give up and go "Maybe next year"? And should she be this active if she is indeed gravid?
