This is likely very normal. How long have you been working out? It's not uncommon when we start or intensify a workout to see an upward shift in weight. This is temporary, and is a normal reaction to the demands we're placing on our bodies: www.sparkpeople.com/community/ask_the_expe
It could also be hormones; women often see a temporary gain right around the time of their menstrual period.
Have you been eating out a lot? Are you tracking sodium? I can gain as much as 5 lbs after a single night out eating because of the insane sodium content in restaurant food.
It takes 3500 calories to gain a pound. In order to truly gain 6 lbs of *fat*, you would need to have eaten at least 21,000 calories OVER maintenance this week. Did you eat that much? If not, I wouldn't stress. Try to eat clean, drink lots of water to stay hydrated, and give it time to even out.
