Dear holabckgrl,

Some women notice pregnancy symptoms as early as a week after pregnancy begins — when a fertilized egg attaches to the wall of a woman's uterus. Other women don't notice symptoms until a few months into their pregnancy.

Symptoms of pregnancy include a missed period, nausea, and inexplicable fatigue. Other indicators are sore or enlarged breasts, headaches, and frequent urination.

Taking a pregnancy test is the only way a woman will know for sure if she is pregnant. She can take a home pregnancy test or go to a health center for testing.
