how early can you have pregnancy symptoms

Pregnancy symptoms can start as early as 1 to 2 weeks after conception, even before a missed period. Early signs often include implantation bleeding or spotting, mild cramping, breast tenderness or swelling, fatigue, and heightened sense of smell. Nausea (morning sickness) typically begins around 4 to 6 weeks but can start earlier for some women. Frequent urination may also be one of the earliest symptoms as hormone levels rise in the body.
