Can blood test show if I am pregnant. If urine test showed negative?

Can blood test show if I am pregnant. If urine test showed negative?

Blood tests can detect this shortly after implantation as well as urine tests that are sensitive, but less sensitive blood and urine tests need 3-4 more days to become positive. No two people are alike either, so that can cause variations also. Time and a specific quantitative test can best confirm this, so see your dr. To be sure. ...Read more

I had a negative blood test and two positive pregnancy urine tests, and a negative urine test also. But it's 6 days before my missed period still?

Can repeat in 1 week: Might be pregnant. A urine pregnancy test, done correctly, gives a reliable result 3 weeks after sex (3 weeks after when conception might have occurred), or 1 week after missing a period. If done sooner, a positive result is likely real, but a negative result may be due to testing too soon, and thus lead to a repeat test. If a woman gets her normal regular period, then she is not pregnant. ...Read more
