What do I do

I had created a campaign with a budget of €20 per day with a single creative only in Italy. I publish everything free only with restrictions on age since I am a streetwear brand for men 18-40. In the first week I received around 60 additions to the cart and 45 purchase starts but zero purchases. Then I decided to detach it. Now I would like to reactivate it. Am I right or is it better to create a new one? Also, did I wait too little? Should I let her go?
