Oh yes! Tests are only about 85% accurate. And some conditions might cause the test to fail more often.
More than likely NO! My cousin was 6 months pregnant and her sister who was not took a pregnancy test to see if she were. The pregnant cousin got a negative result and the sister got a negative result. I would trust my doctor before a home pregnancy test. They do not always work.
Go to your doctor.
You are pregnant
You are pregnant
if you have only 1 line after taking your home pregnancy test it mean that you are NOT pregnant, and if there are 2 lines on your home pregnancy test, then you are pregnant but should go to a docotor to confirm it.
The easiest way to know if you are pregnant or not is to take a home pregnancy test or to see your Dr.
I am not 100% sure what you mean by scan, but in my situation a pos test (both at home and the hospital) and nothing showing on the internal ultrasound confirmed an early miscarriage.
A home pregnancy test is most likely to be accurate if it is positive meaning if you had a negative test you should be monitoring if you could be pregnant. You could have taken the home test too early to detect pregnancy. The best thing to do is to go to the doctor and get a test done there to rule out pregnancy.
That you're already pregnant!
if it says pregnate it could be a false positive meaning you could have cancer instead
no
Weak positive is only about the test, and not about the pregnancy as such.Basically it says that the test isn't quite sure whether you're pregnant or not. Repeat the test and see what it says the next time.
