Leaps- can they be off?

Ma

So my LO was due August 5 but born exactly a week early (July 29). So she’s 5 weeks and this week was super hard with her fussiness and daytime sleep. My wonder weeks app says her 5 week leap will be next week because it based on her due date. Buuuut I feel like she already went through it. Could it be based on her birthday? Anyone else who had their baby early experience this? Thanks!
