How is nausea supposed to feel?

For me, morning sickness felt like I needed to throw up. All day long, and it didn't kick in until I was 3-6 weeks along.

If you're 5 days away from an early pregnancy test chances are you aren't experiencing any pregnancy symptoms yet. The pregnancy hormone hcg is responsible for pregnancy symptoms like morning sickness, but the body doesn't start producing the hormone until the fertilized egg has implanted, which happens an average of 4-6 days after conception. And then it takes at least a few days to get a high enough level of hcg to start producing noticeable symptoms.
