I launched my store around 3 days ago, I had 134 sessions but still no sales, what am I doing wrong?

Hello there,
This is my 1st experience ever in ecommerce business, and I launched on Monday, sharing around in social media, I also did a small ad on facebook, I had visitors, but still no sale.
People had given me positive feedback, but I am still nervous about getting my 1st sale… What should I do from here? keep ads on facebook, keep sharing around?
Any help would be highly appreciated
