Urine pregnancy test positive one week with blood hCG of 1 and the next week urine pregnancy test negative?
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

Yes: Its possible to get an early negative home pregnancy test. You hormone levels usually double every 48 hours at first.

Timing: It is possible that the urine pregnancy test detected HCG that was in the urine even as a pregnancy was failing (impending miscarriage) but by the time a blood test was done, the miscarriage had already occurred and the levels of the HCG pregnancy hormone were cleared. Alternatively, it could have just been a false (+) urine pregnancy test. ...Read more

Faint positive hpt w/ first morn urine, neg dr. Urine test later that day, blood test came back post. Why was drs urine test neg? Early testing?
Pregnancy tests: Blood tests are more sensitive than urine tests, especially in early pregnancy. First morning urine is usually more concentrated than urine produced later in the day. Eating and drinking can dilute the urine enough to cause a false-negative result. That is why the blood test is done for confirmation. ...Read moreSee 2 more doctor answers
2 positive Urine test and 1 positive blood test for pregnancy, today Nov 19 I have a negative urine test and my period came. Cab I still be pregnant?
Hmm, well...: The negative test and fact that your period is now present would go against being pregnant. It does sound as if you were pregnant though in the recent past. Miscarriages are more common than you would think, and maybe your body was not ready for pregnancy. Not definitively sure though, ..you need to see the GYN Doctor as you need an exam to treat you either way. Best wishes, God Bless ...Read more
Is I it possible to have negative urine pregnancy test but positive blood pregnancy test. Why do the urine test keep coming out negative?
Possibly.: These tests are good, but like all tests, can have variations. 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 moreSee 1 more doctor answer
