That would make sense, since this season is just a continuation of the last episode from spring of 2012. Still...
Met in spring of 2012.
Not two years later, engaged. Call it fall of 2013, that's about a year and a half, which would fit the narrative.
Even with a very brief engagement, they get married by mid 2014 and assuming star wars was LATE 2015, it just works, and still involves almost a wedding night pregnancy. And that assumes a super fast engagement to make it work. It's not impossible, but after setting this as a big romantic narrative, a quick engagement and immediate knock-up is kinda disappointing.
