Is it too soon?

Kara • Your friendly neighborhood hypochondriac

So I'm only 4 weeks and 4 days, and I have been having extreme Nausea and just a gross feeling in my tummy like a sour stomach,

I can't stand the smell of smoke, (which i hated anyway but could tolerate) eggs, or coconut (my favorite perfume smells like coconut so that's upsetting!)

Could these symptoms be in my head or is it possible that it's true?
