Women who are 16 weeks pregnant are well into their second trimester. Most have already overcome the worst of the morning sickness phase. They are now at the point of actually being able to enjoy pregnancy. In these next couple weeks, women find they are transforming almost as much as their unborn child. At 16 weeks pregnant, you can expect a number of things to occur in your body. At officially four months, your uterus will be stretching and expanding. The blotchy skin season has long since passed and you are simply glowing! People notice your beauty and developing tummy.

Standard features of most pregnancy calendars include: how to take care of yourself throughout each stage of pregnancy; tips on how to meet increasing nutritional needs while staying physically fit; and how much weight you should gain during pregnancy. Some may also include a detailed outline of your baby's weekly development and instructions from the experts on how to ensure that you both progress the way that you should. Many pregnancy calendars can be customized to fit your own unique personality and include spaces for a diary and a record to important dates.

13th to 16th week

This is the time when you can determine the gender of your baby, although not always with complete accuracy. In the fourteenth week, you can hear the heartbeats of your baby with the help of a stethoscope. Also, you can feel the movements of your baby, as her bones harden.

A normal pregnancy usually stretches over 40 weeks. Pregnancy complication arises, if delivery happens before 37 weeks. This occurs when the foetus membrane ruptures untimely. Premature rupture of membrane (PROM) is the most common cause of premature birth and happens in about 10-20% pregnancies worldwide. Studies indicate that while vaginal infection, improper diet, etc., increase PROM risk, the deficiency of Vitamin C is a major contributor. Vitamin C, found in fruits and vegetables, is critical for the maintenance of foetal membrane.

Morning sickness

Despite the name, the nausea or vomiting you experience may occur at any time of day.This is one of the first symptoms you might experience. It may start as early as one week after conception, however, it typically 6 to 12 weeks

Slight spotting

when the embryo attaches to the lining of the uterus, it may disturb some of the lining which is shed as light pink or light brown spotting-much lighter than a normal period. This is normal and would happen about 8 - 10 days after ovulation (actually just a bit earlier than your period is due).

Tender/Swollen Breasts

Many women experience tender breasts even before/during their menstrual period, so sometimes this sign may not necessarily point to pregnancy. However, if other symptoms on this list are occurring, then this symptom is more likely to be related to pregnancy. This discomfort should decrease after 12 or 13 weeks as your body adjusts to the changes in hormone levels.

Nausea

This is a very common -- and awful -- early pregnancy symptom. Some lucky women don't experience nausea at all! "Morning sickness" is a deceiving term, because nausea can occur at any time of the day, and in some cases, it lasts ALL day! Nausea can last part of the pregnancy, and sometimes during the entire pregnancy.
