Legally you can still visit her after she files the I-130, but yes, probably a good idea for her not to file it until she gets citizenship. Although it might be quicker if she does it now as Reba explains, depends on when she reckons her citizenship will come through I guess as to whether it's worth the hassle.
So given that it's now December, in theory you can re-enter in January to visit her because it's six months in a calendar year.
The problem is that USCIS sometimes get iffy if you tell them you have someone down there you're thinking of getting married to, but legally they can let you visit, even after she files the I-130 to sponsor you and you're married.
Just depends on who you get at the POE and how convinced they are that you're only entering temporarily.
