The most common early sign of pregnancy is a missed menstrual period. Sometimes a woman has a period, but it is shorter or lighter than usual. If she normally has irregular periods this sign may be hard to notice. Another sign is having to urinate more often. This is caused by hormone changes and growing pressure on the bladder.
Some women feel sick or nauseous.
This may be slight, or may make her throw up. Hormone changes cause this also. Eating dry soda crackers before you get out of bed and small, frequent meals may also help. Breasts may become tender, sore and larger. The area around the nipples may become larger and darker.
