When you start feeling pregnancy symptoms is usually about 7 to 14 days after a missed period, or around 5 to 6 weeks after the first day of your last period.
In most cases, the first sign of pregnancy is a missed period. This is often followed by other symptoms that appear gradually, such as nausea, vomiting, breast enlargement and tenderness, frequent urination, and fatigue.
Even if symptoms have not started yet, a blood test that measures the beta-hCG hormone can detect pregnancy in the early weeks. This test can usually be done about 6 to 8 days after pregnancy begins.
Some women may also experience less common early pregnancy symptoms, such as mild cramping or light bleeding. This usually occurs about 1 to 2 weeks after pregnancy begins due to implantation of the fertilized egg in the uterus.
If you think you may be pregnant, especially if your period is more than 7 days late, it is best to see your primary care provider or an OB-GYN. They can order tests to confirm whether you are pregnant.
