WASHINGTON, DC (WUSA)--Is she or isn't she?  Is Mei Xiang--the National Zoo's giant female panda pregnant or not?

A spokesperson for the National Zoo tells 9NEWS NOW we could know tomorrow or in a few weeks.  "She is cradling objects and sleeping quite a bit more," says Lindsay Renick Mayer.  However this behavior is consistent with both a pregnancy or pseudo-pregnancy.

Mayer tells 9NEWS NOW Mei Xiang did undergo an ultrasound Tuesday but it did not show anything.  But this really doesn't tell us much either way because detecting a pregnancy is very difficult in a giant panda.

You can watch Mei Xiang, and her male companion Tian Tian, live on the National Zoo's PandaCams.
