Frequent Urination
It caused by the pressure on the bladder as the uterus enlarges during the pregnancy.
Constipation
Constipation during pregnancy can be caused by the iron supplementation or the enlarged uterus make the small intestine shift and suppress the rectum, which slows down the bowel movements.
Nausea and vomiting
In the early stage of pregnancy, the hormonal change results in nausea and vomiting. But symptoms will naturally disappear at the end of the third month for most cases, and only very few will last until delivery.
Cramps, swelling on the lower limbs and varicose veins
Hemorrhoids
Diarrhea, constipation, and straining during bowel movements which can increase pressure on veins, or the enlarged uterus may block blood flow through veins, which contributes hemorrhoids in pregnancy.
Backache
As the baby grows, the mother's belly enlarges, to maintain balance, the mother's posture shifts, which leads to lower back pain.
Heartburn
During pregnancy, the hormone progesterone causes the esophageal sphincter to relax which allows stomach acid to pass into the esophagus and results in a burning sensation.
Tooth and Gum Disease
Tooth decay, gingivitis, gingival hyperplasia during pregnancy, the periodontal (gum) disease worsens because during pregnancy, the Estrogens in the body increase, causing swelling of the mucous membranes, which is prone to bleeding from the mouth or gums.
Regardless of the amount of alcohol consumed, it increases the risk of getting cancer, and that has confirmed by the Committee on Carcinogenicity (CoC). During pregnancy, no matter how much alcohol you drink, you are putting your health at risk. In addition to causing pregnancy bleeding and miscarriage, uterine and vaginal infections, habitual abortion, placental abruption, and stillbirth, excessive alcohol also affects the growth of the fetus in the womb.
Heavy drinking during pregnancy is associated with Fetal Alcohol Syndrome (FAS), a disorder which occurs in infants. Babies with FAS have:
Your doctor or specialist should know if your child has FAS through a series of physical examinations. There is currently no medical treatment for this disease, and the management of FAS lies in special education programmes and behaviour therapy for the child.
FAS is a tragic but preventable disorder. It can be avoided if you don't consume any alcohol at all – while you're pregnant or even if you are trying to get pregnant. If you think you may have an alcohol addiction, then you may want to think about getting help.

Interestingly, women who are expecting often lose their taste for alcohol, so giving up might be easy even for regular drinkers. However, if you are still struggling to get your alcohol intake down to zero, here are some practical tips which may help you during pregnancy.

Importance of safe use of medicines before and during pregnancy
Improper use of medicines may also lead to premature babies, underweight babies, and stillborn births, and in less desirable cases teratogenicity and birth defects. However, in patients with existing medical condition, premature withdrawal or negligence of due medical treatment may result in long-term complications on both the mother and the baby. Pregnant women should always seek medical advice prior to consume or discontinue any medications.
If you are trying to get pregnant soon, ask your doctor or pharmacist's advice before taking any medication and do not arbitrarily use drugs or take herbal or folk remedies unnecessarily.
If you have taken any medication, including prescription or over the counter drugs or dietary supplements when you are or might be pregnant or you may have gotten pregnant as no contraceptive method used, please tell your doctor or pharmacist.

Weight control for expectant mothers is very important during pregnancy. Underweight or overweight is bad for both the pregnant woman and baby. It is best to understand how to properly take in nutrients from the early stage of pregnancy and reasonably regulate the weight during pregnancy. The weight gain during pregnancy depends on the weight before pregnancy.
Your Body Mass Index is a key indicator. You can work it out this way.
Step 1: Note your pre-pregnancy weight in kilos
Step 2: Measure your current height
Step 3: Your BMI = weight divided by height squared

Not gaining enough weight increases the risk of a premature birth. One common reason you may find it hard to put on the kilograms is morning sickness — see your doctor if this becomes a problem. Ideally, you should try to eat three main meals a day, plus two or three snacks in-between.
It's important to note that weight gain is normal in pregnancy, and you should not dive into a radical diet programme at this time. Small, healthy changes to your diet are recommended.
Watch your intake of high-fat or sugary foods with these simple tips:

Stretch marks have a lot to do with genetics and physique. Your uterus expands when the fetus grows along the pregnancy journey. Your abdominal circumference is getting bigger too. When the skin pulled tight, the connective tissue, like collagen and elastic fiber, will be stretched to beyond its elasticity limit. Another possible reason is the increased level of epinephrine and steroid during pregnancy may weaken the expansion ability of the connective tissue. Stretch marks are more likely to develop in multiple-pregnancy than single-pregnancy. They often develop in areas like belly, breasts, buttocks, and thighs. Often starts as reddish wavy stripes, but after pregnancy, the marks gradually fade to white or grey lines. Unfortunately, once the stretch marks has developed, there is almost no way to get rid of them.

Therefore, it is recommended to start with prevention by managing weight gain during pregnancy. Keep the weight gain within the normal range by gaining no more than 2kg per month. The total weight gain should be around 11-14kg throughout the pregnancy. At the beginning of pregnancy, you can apply the maternity moisturizer and massage gently on tights, belly, and chests twice daily, morning and night. It helps to reduce skin tension and increase the elasticity of epidermis and dermis. It also helps reduce the opportunity of stretch marks development by stretching the skin further. Besides, applying lotion and massage helps to moisturize the skin depending on the skin condition, and carry out the touch stimulation and fetal education at the same time.

Pregnancy and childbirth are parts of the natural biological process. Uterine contractions will cause pain or back ache. The contractions make the uterus soft and expand. Therefore, they are also a normal biological change, which signals the baby is about to leave the uterus and will arrive in the outside world soon. The pain brings discomfort and may cause fear to those who are not familiar with the contractions. The contraction is an indicator of vaginal delivery. It causes the cervix to thin and dilate and helps the baby to descend into the birth canal. Don't panic over the labour pains as they are part of the labouring process, and there are many ways to help you manage the pain. Keep your mind relaxed by staying calm and thinking positively. Let your body guide you through the labouring process so that your muscles will relax and have a smooth delivery.
The cervix dilates gradually, and the baby turns gradually out of the uterus. The length of the labor process depends on the number of births the mother has given, the time separation from the previous birth, the emotional condition, the fetal position, the size and shape of the pelvis, and uterine contractions. Therefore, labour may take a while. Typically, it takes 12 to 18 hours of labour for the first child and approximately 8 to 10 hours for the second one. Patience is required. In recent years, expectant mothers have better nutrition status, they tend to exercise less often and their babies are relatively large, delivery may be prolonged, which will require the expectant parents to be more patient. The expectant parents should start receiving prenatal education a few months before the due date to understand the changes during labour, ways of relieving pain naturally, and the different types of pain relievers. It won’t be as effective to learn about pain management techniques after the contraction starts.
The following are the basic ways of relieving pains and discomfort during labour.

Within a few weeks of the expected date of delivery, the baby's head would lower toward the pelvis that drops the pressure on your stomach and diaphragm. You will feel more relaxed, have better appetite and breathe smoothly.
Virginal discharge or losing your mucus plug
Your cervix begins to dilate as you get close to labor, a small amount of blood or blood-tinged mucus is released from your cervix and makes its way out of your body through vaginal. If you're bleeding heavily or seeing signs of blood long before your due date, do check in with your doctor right away.

Contractions and back pain
If caused by uterus contractions, you will feel:
Your water breaks (a large amount of fluid starts to flow out of the vaginal area)
During pregnancy, your fetus is protected by a fluid filled membranous sac called the amniotic sac. At the beginning of or during labour, your membranes will rupture. Regardless of whether there are regular contractions or not, try not to walk around and go to a hospital as soon as possible.
Other signs to take note of:
See your doctor right away if you have any of these symptoms during your pregnancy.
