By saying you ended TOM Thursday, do you mean yesterday (not Thurs a week ago?). You might still have some TOM-related weight.
For me personally, I gain about 4 lbs during TOM, and lose it only 3 days after it ends. The reason I KNOW that is because I weigh daily, and therefore am aware of my upward and downward fluctuations. Over time, these made a clear pattern for me...that I gain X amount during TOM that goes away on a specific day. Knowing that pattern made it much easier to be OK with the fluctuations I saw, because they made sense.
