Pregnancy is a special period in a woman's life, and also unique in a man's. You may already have learned a lot from your doctors and friends who have experienced pregnancy, or from internet. However, something could be neglected by you doctor because it is of no medical importance,and something neglected by your friends because they may not even have noticed that. These tiny things may effect your daily life as a pregnant.
1. The Nesting Instinct
It's the urge to clean, organize, and decorate before the baby arrives. As your due date draws closer, you may find yourself cleaning cupboards or washing walls — things you never would have imagined doing in your ninth month of pregnancy!

2. Inability to Concentrate
In the first trimester, fatigue and morning sickness can make many women feel worn out. But even well-rested pregnant women may experience an inability to concentrate and periods of forgetfulness. You can combat this forgetfulness by making lists to help you remember dates and appointments.

3. Mood Swings
It is just similar to premenstrual syndrome--your breasts swell and become tender, your hormones fluctuate, and you may feel moody. If you suffer from premenstrual syndrome, you're likely to have more severe mood swings during pregnancy. You can change from happy to sad in a very shot time. Some trifles may make you outraged.Mood swings are incredibly common during pregnancy, although they tend to occur more frequently in the first trimester and toward the end of the third trimester. About 10% of pregnant women even experience depression during pregnancy.

4.Skin
It's caused by hormonal changes and your skin need to strech to accommodate a larger body. Skin stretching over the abdomen may cause itchiness and flaking.
Pregnant women experience an increase in blood volume to supply the uterus and extra baby. The greater volume brings more blood to the vessels and increases oil gland secretion.Acne is common during pregnancy because the skin's sebaceous glands increase their oil production.
Some women develop brownish or yellowish patches called chloasma, or the "mask of pregnancy," on their faces. And some will notice a dark line on the midline of the lower abdomen, known as the linea nigra (or linea negra), as well as darkening of the nipples, external genitalia, and anal region. These are the result of pregnancy hormones. Unfortunately, chloasma can't be prevented, but wearing sunscreen and avoiding UV light can minimize its effects.

5.Hair and Nails
Many women experience changes in hair texture and growth during pregnancy. The hormones secreted by your body will cause your hair to grow faster and fall out less. But most women lose a significant amount of hair in the postpartum period or after they stop breastfeeding.
Nails, like hair, can change noticeably during pregnancy due to extra hormones, which can make them grow faster and become stronger. Like the changes in hair, nail changes aren't permanent.

6.Joint Mobility
During pregnancy, your body produces a hormone known as relaxin, which is believed to help prepare the pubic area and the cervix for the birth. The relaxin loosens the ligaments in your body, making you less stable and more prone to injury. It's easy to overstretch or strain yourself, especially the joints in your pelvis, lower back, and knees.

7.Varicose Veins, Hemorrhoids, and Constipation
They may be all caused by pregnancy.

Varicose veins often disappear after pregnancy, but you can lessen them by:
avoiding standing or sitting for long periods of time
wearing loose-fitting clothing
wearing support hose
elevating your feet when you sit

Hemorrhoids are varicose veins in the rectum. Because your blood volume has increased and your uterus puts pressure on your pelvis, the veins in your rectum may enlarge into grape-like clusters. Coupled with constipation, another common pregnancy woe, hemorrhoids can make going to the bathroom downright unpleasant.

Constipation is common throughout pregnancy because pregnancy hormones slow the rate of food passing through the gastrointestinal tract. During the later stages of pregnancy, your uterus may be too large and push against your large intestine, making it difficult for waste to be eliminated. Constipation can contribute to hemorrhoids because straining may enlarge the veins of the rectum.

To prevent them you need: eating a fiber-rich diet, drinking plenty of fluids daily, and exercising regularly. Stool softeners (not laxatives) may also help. If you do have hemorrhoids, see your doctor for a cream or ointment that can shrink them.
