The Third Trimester of Pregnancy: Weight Gain & Other Changes

Weight Gain

This trimester you should expect to gain about eleven pounds, bringing your total pregnancy weight gain to between 25 and 35 pounds. Remember that your pre-pregnancy weight is important in determining the amount of weight that you should gain. Women who are underweight before they become pregnant should probably gain between 28 and 40 pounds, whereas overweight women should likely gain between 15 and 25 pounds overall. These are only guidelines, however, and each woman's pattern and amount of weight gain will be different. Talk to your doctor about what is right for you and your baby.

Fetal Hiccups

You may notice that you feel spasms in your abdomen and you can't tell if it is a kick or a twitch. You may be feeling your baby's hiccups. Babies can get hiccups in the womb, sometimes even as frequently as several times a day in the later parts of pregnancy. Don't worry - these hiccups do not cause the same discomfort in a fetus as they do in adults.

Clumsiness

Both the retention of water and the laxity of your joints under the influence of pregnancy hormones can lead to clumsiness. You may feel as if you cannot hold on to things with as tight a grasp as usual. There really isn't much you can do about this other than not handling fragile things around the house until after the baby is born.

Feeling Warm and Increased Perspiration

Your basal metabolic rate (BMR) increases in pregnancy by 20% - meaning you are burning more calories even while resting. You may feel overheated and perspire more. Sweating is a good thing because it cools you down, but it also makes you feel in constant need of a shower. Use a good antiperspirant, dress in layers, and drink plenty of fluids to replace what you lose through sweating.

Urine Leakage

As your uterus gets larger and presses on your bladder, you may leak urine. Any increase in abdominal pressure (for instance, when you laugh, cough, or sneeze) can cause you to leak. Once you deliver, this incontinence should improve.

Hemorrhoids

If you haven't had hemorrhoids yet, you may start to experience them now. Hemorrhoids are actually a form of varicose veins and are more common during pregnancy as the uterus presses on the rectal veins, which are already dilated because of progesterone in your body.
