I analyzed it:

When everyone came back to the Enchanted Forest, Aurora was pregnant. Snow White was most likely a few weeks pregnant when Aurora told them Zelena wanted their baby (because the timeline switches to 8 Months Later after the title card in A Curious Thing), and everything that went on from Episode 16 to 20 was a few weeks (because Snow was 8 months pregnant when the new Curse was enacted, and she was in labor at the end of 3x20). Aurora was still pregnant when she told Snow about Zelena wanting their baby, because she was rubbing her belly.

In the timeline of 8 months later, Aurora had already given birth to the baby (and if still a monkey, then it was likely a baby monkey). So no, she's not pregnant anymore.
