How Can You Tell If You're Pregnant?

According to the Mayo Clinic, the quickest way to determine if a woman is pregnant is to use a pregnancy test, which can be taken at home or at a doctor's office. Other symptoms of pregnancy occur during the first few weeks of pregnancy. An early sign of pregnancy is tender, swollen breasts. Breasts may feel fuller, more sensitive and heavier than normal.

The Mayo Clinic lists nausea, vomiting, increased urination, fatigue, food aversions and a missed period as signs of pregnancy. Nausea can occur with or without vomiting and at any time during the day or night. Fatigue is prevalent in most women during early pregnancy due to the increased levels of progesterone. It can present as early as one week after conception. Dizziness, mood swings and constipation are other signs of pregnancy, but they do not occur in all women.

WebMD adds that women may experience cramping or spotting a few days to a few weeks after the egg is fertilized. This occurs when the fertilized egg attaches to the uterine wall. The cramps may be confused with menstrual cramps. Women may experience a milky, white discharge after conception as the vaginal walls increase in thickness. The discharge is normal and may continue throughout the pregnancy.
