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.
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.
- 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.
- 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.
- 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.
