What are symptoms of pregnancy 2 weeks in?

Minimal: Common signs and symptoms of pregnancy usually start occurring by about 6 to 8 weeks and include breast tenderness, nausea (morning sickness), weight gain due to fluid retention, amenorrhea, urinary frequency, mild headaches, insomnia, fatigue, and constipation. Some of these will occur sooner than others during the pregnancy and some will progressively worsen during pregnancy.

Very few: A 2 week old pregnancy is unlikely to bring many symptoms other than spotting as the hormone of pregnancy is in such a low amount. Breast tenderness, nausea, and fatigue are probably most common symptoms of early pregnancy.
