How many weeks is one usually pregnant when you find out from a doctor?

Typically, a person finds out they are pregnant from a doctor around 5 to 12 weeks after conception. This corresponds to 7 to 14 weeks of gestational age, which starts from the first day of the last menstrual period (LMP), even before conception occurs. However, pregnancy tests available nowadays, both urine and blood-based, offer reliable results even before a menstrual period is missed if done accurately a few days before the next period is expected.
