What Is A Pregnancy Test?
Pregnancy tests measure the level of the pregnancy hormone HCG in your urine or blood. HCG can be detected in your blood as early as 6-8 days after conception happens, but not in your urine until a day or two before you expect your period.
Only about 15% of women DON’T suffer from nausea at some time during their pregnancy. Since each woman is different and each pregnancy is different, the severity will vary – nausea does tend to get worse with each pregnancy though.
