What are the symptoms of pregnancy in the second week?

Tender breasts, nausea, dizziness, and drowsiness are just some of the symptoms women face during the second week. As a pregnant mother, a woman should now begin to focus on changing her lifestyle and dietary habits if she has not already done so, as this second week is a crucial turning point in the baby’s development.
During the first week of pregnancy, morning basal body temperature — your body temperature when you are completely at rest — will remain elevated. If you are noticing these changes, you might want to contact your health care
provider to set an appointment to test for the pregnancy.
Although there are few physical changes at this point, you may be noticing internal changes. Digestive issues — like gas, constipation and nausea — may be cropping up. You also may be noticing more fatigue than usual, and mood swings with the changing hormones. Morning sickness may also begin during the first week, though most women won't notice these changes until after the second week of pregnancy.
