How are you hiding it?

I feel so crap and tired and sick I am cancelling plans and flaking on so much stuff. My friends are def going to think I'm a complete bitch. But I feel rubbish and just want to be home. How is anyone else hiding this from their friends and that? I had a miscarriage in October so I am worried and would rather have my first scan before I share but I'm only 8 weeks. How can I keep this up for another month?! 😅😒
