is it possible?

My fiancé tried to conceive on December 7th and 8th. I have noticed a little change in her boobs and belly. Is it just me? Or is that possible... in wondering if I'm just expecting it so I'm thinking it.. I mean I guess it could possibly be her period coming. She never really paid attention to her cycle so we don't know the exact day she should be getting it but I believe it should be sometime this week!
