How can i put my mind at ease?

Hiya ladies, I'm hoping someone can help reassure me 😭 i am 6 weeks and 4 days pregnant today. I had horrible nausea over the weekend which seems to have subsided since then. My problem is that i just don't think I'm pregnant anymore. I can't get this thought out of my head despite having no cramping or bleeding. I can't get a scan done until next Tuesday so i have a lot of time left to worry myself sick. Please help, it's tearing me up 😭😭😭
