Gained Weight!!
Exercise is NEVER a bad thing. It's always the right thing to do. I've been known to go up and down 5 pounds in just a day or two - we're women and it happens. Maybe a little more salt than usual?? Maybe a few more carbs? Sometimes your body just needs to reset. I don't know how far you are in your journey, but if you are anywhere near 3 weeks out, then it may just be the dreaded stall/gain that everyone seems to experience. I have been up, down, stalled, etc. And I have driven myself crazy with what the scale says. Finally, I've started paying less attention and weigh myself less often, and I'm much happier, and the progress even seems quicker when I'm not looking at every pound lost. I went to the doctor today, and I lost 22 pounds in this last month...and I thought my weight loss had really slowed down because I was constantly looking at it. So, don't sweat it, it will come off...just keep doing the right things :)
