As you move into the second half of pregnancy, you will begin to notice many physical changes happening in your body. While these aren't always pleasant, it helps to know they are quite common. You may or may not experience all of these changes, and you may find some are more intense at different times during pregnancy.

Here are some of the most common changes women experience during these last months of pregnancy:

The skin on your belly may itch as it grows. Aches may occur along the sides of your abdomen as ligaments stretch to support your uterus. Keep your skin soft and moisturized, and avoid quick, jerky movements to prevent pulling the ligaments.

You may feel the need to frequently urinate as the weight of your uterus presses on the bladder.

Mucous membranes in your nose and mouth are affected by the increase in hormones during pregnancy. Some women have a stuffy nose and nosebleeds, as well as spongy, tender gums. Good dental hygiene is a must.

Varicose veins and hemorrhoids may appear. These are caused by the increased pressure on your legs, pelvic veins, rectum, and perineum, and by the increased blood volume in pregnancy. Avoid standing for long periods and try to elevate your feet and legs whenever possible. Your physician may also recommend special support pantyhose. Avoiding constipation and straining may help to prevent hemorrhoids, or to lessen their discomfort.

You may notice a white-colored vaginal discharge called leukorrhea. A watery, colored, or bloody discharge may signal possible complications and should be checked by your physician immediately.

Skin pigmentation may change on your face due to the pregnancy hormones. Sunlight can aggravate this condition called chloasma, so wear a hat or sunscreen if you will be outdoors.

Heartburn, indigestion, and constipation may be a concern. Eating small, frequent meals and taking an antacid approved by your physician can help.
