Hi! Welcome to healthcaremagic.com. One of the very noticeable early signs of pregnancy is tender, swollen, somewhat sore breasts. When you become pregnant, your body begins preparing your breasts for producing milk and breastfeeding. Hormones start increasing. In addition to breast tenderness and swelling, your nipples may feel sore or extra sensitive. Some women notice their nipples darken in color. Stomach ache or heartburn -This pregnancy symptom is caused by the uterus starting to swell and pushing against the stomach and other organs as it grows. Also, increasing levels of hormones may slow down digestion and bowel functions to allow the body to absorb as much vitamins, minerals and nutrients as possible from foods.Smaller more frequent meals are easier to digest. Drink plenty of water and eat fruits, vegetables and perhaps some raisin and bran cereal to help regularity.
