There is no reason to write Ginny's pregnancy into the show, and honestly, it wouldn't make sense. From the time that Neal was born to the present is relatively short. Frozen (4A) happened immediatly after the birth, and was probably 1, or maybe 2, weeks total for that half of the season. 9 weeks for the time from when Rumple was banished until Isaac wrote his story. Add 6 weeks for the Camelot/Dark Swan story, that would make Neal somewhere between 3 and 4 months old.

And while it is possible for a woman to become pregnant within that amount of time, it is not common.

So, from a story-telling perspective, Snow being pregnant again makes little to no sense, and really does not server any useful purpose for a plot line. (Unless, of course, it is used as a plot device to write Mary Margaret into the background)
