What are the first signs of pregnancy? One of the clearest signs is not menstruating. If a woman does not have her period as usual after having had sex with a man without using any contraceptives, it is often a sign of her being pregnant. Another sign of pregnancy is swelling or tenderness of the breasts. Some women grow more pubic hair on the lower belly and for many the colour of the area around the nipples of the breasts becomes darker. Also, about half of all pregnant women feel sick and some vomit. Many women need to pass urine more frequently, some feel tired and dizzy, especially in the first three months. Sometimes Women have strong desires or dislikes for specific foods. If woman has any doubts, she should go for a urine test at the clinic in order to find out whether she is pregnant or not.
