But I think. I took it to early and what does it mean by all the signs of pregnancy and it doesn't show but you hcve the breast growing and nausea etc?

Please see below. If you feel that you're having pregnancy symptoms but a home pregnancy test was negative, please see your doctor. Your doctor can examine you for signs of pregnancy and may order a pregnancy blood test, which is more sensitive than the home pregnancy test. If it's normal, too, your doctor can evaluate you for other causes.
