No. The only thing that will cause a negative pregnancy test is no HCG in your Urine. A pregnancy test will only become positive when HCG has been detected in your Urine. If it does not become positive then no HCG has been detected. Test in a week and if it is still negative then see your doctor for a blood test or confirmation.

If you had 3 positive pregnancy tests then a negative and started bleeding and having abdominal pains and then a blood test was negative were you ever pregnant in the first place?

It really depends on how long after the bleeding you had the blood test. If you had the blood test within 5 days after the bleeding and it was negative then its possible you wasnt pregnant. But if you had the blood test less than 5 days after the bleeding and it was negative, then you was not pregnant. But a pregnancy test should only go positive when HCG has been detected and this is only during pregnancy.

Hello. A positive pregnancy blood test is never wrong. Congratulations.


Are you pregnant if you're 48 days late and have had two positive home tests and two negative blood tests?

Hello. The two positive home pregnancy tests mean HCG has been detected in your urine. When HCG has been detected this is a strong indication that you are pregnant. The blood test over rules the result of the home pregnancy test and means you're not pregnant. BUT if the blood test was a Qualiative then there is a possibility it was negative because you are not as far along into your pregnancy as you suspected. Go back to your doctor and ask for a QUANTITATIVE BETA HCG pregnancy blood test - this test is highly accurate and measures the amount of HCG in your blood unlike the Qualiative blood test which just gives you a yes or no answer. You will need to write down the name of this test as it can easily be mistaken for the qualiative one. Remember QUANTITATIVE. Good luck. :o)

According to the American Pregnancy Association, yes, pregnancy does increase the risk of cerebral palsy, but not pregnancy alone. Factors during pregnancy play a large role. Issues such as infections during pregnancy, blood diseases, ,acterial meningitis, and lack of oxygen to the fetus can increase chances. Pregnancy will not increase the chance of palsy within the mother.

Can you still be pregnant if you had an irregular period and you have symptoms of pregnancy but a pregnancy test was positive then took another one and it was negative?

It is very rare that a pregnancy test would come up positive if you weren't pregnant, because it detected HGC in your urine. In most cases if a HPT is wrong it comes up negative. If your period was irregular and you had a positive result you are most likely pregnant. I would try another test, or go see a doctor and request a blood test.
