Is it possible to be pregnant and have a negative pregnancy test?

If it's very early in your pregnancy, your body might not have produced enough hCG yet. In that case, you'd get a negative result at first. Also, some tests are more sensitive than others, and no test is 100 percent accurate. And a few women have such low levels of hCG during pregnancy that home tests can't measure it.

How many weeks pregnant do you have to be to have a positive pregnancy test?

Most doctors recommend that you wait until the first day of your missed period before taking a urine pregnancy test. This is usually about two weeks after conception. However, some tests are more sensitive than others and can be taken earlier.
  • Do pregnancy symptoms start after missed period?

    Pregnancy symptoms at 4 weeks. Normally you get your period about 4 weeks from the start of your last period, but if you're pregnant, the clearest sign at this point is a missed period. Many women still feel fine at 4 weeks, but others may notice sore breasts, fatigue, frequent urination, and nausea.
  • How many days after conception is implantation?

    Implantation is the process by which a fertilized ovum (egg) implants into the uterine wall to obtain oxygen and nutrients from the mother. This usually occurs between 6 and 8 days after conception. Conception itself can occur anywhere between a few hours and 5 days after intercourse.
  • Can a HCG blood test be wrong?

    A woman might get her period a few days after a positive pregnancy test and assume she had a false-positive result. However, it could be that she was pregnant but miscarried very early on. “It's not that the test is wrong—it was completely accurate at picking up the hormone [hCG]," Dr. Williams says.
