Be alert if these symptoms appear during pregnancy, there may be problems in the uterus.

If there is severe pain in the stomach which does not go away during pregnancy. Or if there is pain in the tip of one shoulder or below the ribs, then you should immediately consult a doctor. Bleeding in the second or third trimester may be a sign of a more serious condition, such as placenta previa, placental abruption, premature labor or incompetent cervix.

Many pregnancy symptoms, such as missing periods (amenorrhea), nausea (morning sickness) or fatigue, can also be caused by stress or illness. So if you think you are pregnant, get a pregnancy test done at home (urine test) or visit your doctor, who will conduct a urine test, blood test or ultrasound scan.

During pregnancy, the breasts become full, swollen and tender. These changes are similar to those you may notice a few days before your period. During pregnancy, the skin around the nipples becomes darker and the veins in the breast become more visible.

It is common to feel extremely tired in the beginning of pregnancy. This is most likely caused by a massive increase in the sex hormone progesterone. Progesterone is needed to maintain the pregnancy and help the baby grow, but it also slows down your metabolism. Try to get a little more sleep or rest whenever possible during this early stage. Around the fourth month of pregnancy when the placenta is well established, your energy levels will probably increase again.

Fatigue during pregnancy can also be caused by anemia, which is usually caused by iron deficiency. Eating iron-rich foods is important in preventing iron deficiency anemia during pregnancy. Medical treatment of anemia in pregnancy usually involves taking iron tablets. Sometimes iron infusion (iron medicine given by drip) is required. This requires hospitalization, but it only takes a few hours. Some iron infusions may be given by your GP.
