Not every woman has a regular menses, so it may be necessary to have other symptoms to indicate whether she may or may not be an expectant mother. Many signs exist, some as early as within ten days of conception.
Nausea and Vomiting
Considered one of the classic signs of pregnancy, nausea and vomiting is technically referred to as "morning sickness," even though it can occur at any time of the day or night. Morning sickness is due to increased levels of estrogen, which begin to rise from the moment of conception. Increased estrogen levels cause the stomach to empty more slowly, making it easier for nausea to set in. In some cases this nausea is accompanied by vomiting.
Swollen Breasts
Often noticed within one or two weeks after conception, swollen breasts may also be accompanied by tenderness, which is typically due to increased hormone levels. The swelling, however, is due to an increase in milk production as your body prepares you for breastfeeding.
Spotting
Known in the medical community as "implantation bleeding," spotting generally occurs within ten to 14 days after conception and occurs once the fertilized egg has attached itself to the wall of the uterus. Generally taking place about a week prior to your period, it may be accompanied by mild cramping and will be lighter in color than your normal period--usually pink rather than red.
Exhaustion
Many women typically feel completely drained of energy. This is due to increased levels of the hormone progesterone, which has a tendency to make you want to sleep most of the time during the first few weeks of your pregnancy.
