Yes, you could still be pregnant maybe its too early to tell.
If you have a negative test and a period you are probably not pregnant. If you are paranoid about being pregnant you may be seeing symptoms that are not really there.
No, you can suffer the affects of a false pregnancy.
Yes it is very possible that you could still be pregnant my tests didn't show I was pregnant until I was between 2-3 weeks pregnant
It is extremely unlikely that you are pregnant.
Yes you can be pregnant.
Yes it is called a positive negative and the tests are only 99.998 precent correct
You could by a small chance, but, you might also imagine the symptoms (phantom pregnancy). Or your pregnancy is too small at the moment. Try testing again in a week or two (when your period hasn't started). If still negative and you got the symptoms and no period then go see a doctor.
you might be pregnant, but i doubt it. the symptoms were probably just pms, and if you were worried/excited that you might be pregnant, the stress could have delayed your period. if you dont get your period by the end of the week , take another test - if you are pregnant you may have just tested too early. if you still think you are pregnant , but still get a negative result, see your dr.
Home pregnancy tests are not 100% accurate, there are many reasons that they can read falsely. Visit a doctor and have a proper lab test done for more accurate results. That said, it is possible to have some symptoms of pregnancy, without being pregnant.
