When do you know for sure are pregnant?

A pregnancy can be confirmed through several methods:

1. At-Home Pregnancy Test: Home pregnancy tests are easily accessible and can be purchased over the counter at most pharmacies. These tests detect the presence of human chorionic gonadotropin (hCG), a hormone produced during pregnancy, in your urine. A positive result on an at-home pregnancy test usually indicates pregnancy, but it's recommended to confirm with a healthcare professional.

2. Blood Test: A quantitative blood test, also known as a beta-hCG test, measures the exact amount of hCG in your blood. It can detect pregnancy earlier than urine tests and is used to confirm pregnancy or monitor hCG levels during the early stages.

3. Ultrasound: An ultrasound examination, also known as sonography, uses sound waves to create images of internal organs, including the uterus. An ultrasound can provide visual confirmation of pregnancy by detecting the presence of a gestational sac, fetal heartbeat, and other anatomical features.

4. Clinical Examination: A healthcare professional, usually a doctor or midwife, may perform a physical examination to check for signs of pregnancy, such as changes in the cervix, uterus size, and breast tenderness.

It's important to note that a definitive diagnosis of pregnancy is usually made after confirmation by a healthcare provider. They may use a combination of the above methods, along with your medical history and symptoms, to determine if you are indeed pregnant.
