Two weeks is way too early. I think it helped with my hips, but the tummy itself, there are gentle exercises you can do to help close up your muscle separation. It took three months for my tummy to go almost flat again, but it's still a bit flabby. You don't want to lose the weight too fast either, in case you get skin folds there, so takes thing easy and keep using the stretch mark oil/lotion and massage it well.
