Question on Chloe's ultrasound

 Since I missed most of the show due to the McChrystal thing (which I was very annoyed at by the way since it could have aired during the news!), I am confused as to why in the last few minutes of the show, Carly was doing an ultrasound on Chloe.  What happened that Carly needed to do that?  I don't get Soapnet anymore so I couldn't watch it later on that network.
