Pregnancy Week By Week

The pregnancy calculation, for the above-mentioned purposes

, is done such that the pregnancy weeks are counted from the first day of LMP i.e. the Last Menstrual Period. Therefore, as per this calculation procedure, in the first two weeks of pregnancy, there actually is no pregnancy. The eggs do not fertilize till about two weeks and the baby is therefore actually expected within 38 weeks of fertilization.During pregnancy of about 38 to 40 weeks, women undergo a number of internal and external changes. Though external changes in pregnant women are noticed by others, internal changes are known to and experienced by the pregnant women only.Pregnant women, even in the era of information technology revolution, feel depressed about the mysterious goings on inside their bodies because there still exists widespread ignorance about pregnancy. They do not know what exactly pregnancy is and how to negotiate with the changes taking place inside and outside the body. As a result of this, women demand a guide to pregnancy which serves as a survival kit during pregnancy. It equips them psychologically and physically to face the new situation while preparing to give birth to a new baby.The second trimester comprises week 15 to week 26. In the beginning of this trimester i.e. week 15, the baby begins movement of head, lips, and feet. Due to upward movement of uterus, the pregnancy symptom of frequent urination would abate by week 16. Baby begins blinking, sucking, and swallowing in week 17. Due to myelinization of nerves, nerve cell transmission registers a significant increase making body reflexes quicker. During week 20, baby begins to sleep and wake on regular basis. By week 24, baby's heart beat becomes so distinct that it can be heard by placing an ear on stomach. And before the second trimester ends, brain wave activity commences for ears and eyes.
