I've stayed the same this past three mornings, but I'm not panicking too much. My weigh-in isn't very reliable on days I'm at work early, because I need to weigh before instead of after LittleMan's morning breastfeed. I'm hoping for great things on Saturday, though!
I like to see fluctuations like yours because then at least I know my body's doing something. When I stay the same too many days in a row I start to think that my scale's broke!
