You can take Tylenol for the cramping . It's pretty normal in early pregnancy . As for the nausea , try eating crackers when you first get up . It works . If that doesn't work, you can take an antacid to ease your stomach.
I am 6 weeks 4 days as well and I feel the exact same way. Im nauseous all day and I feel as if my stomach is always empty causing it to hurt.
