The second trimester runs from week 13 to week 28. Morning sickness from the first trimester reduces and eventually varnishes. Form the thirteenth week; anticipate gaining about 1.6 kilograms every month until delivery. Numerous changes happen to your body. The breasts expand in size due to fat deposition. The nipples get tender and darker. At this time you may need to get a bigger bra and change to maternity clothes. Progesterone and estrogen increases blood flow to the milk secreting glands in the breasts. The ducts and the alveoli tissues of the glands increase in size in readiness for milk production. The Montogomery glands (glands on the areola) become conspicuous. They secret fluid which lubricates the nipples and kills bacteria. A hormone called prolactin triggers the secretion of colostrums in small amounts.

The uterus contracts as it expands to make room for the growing baby. These are called Braxton Hicks contractions. They are usually minor and exert pressure on the lower abdomen which starts to swell as well. When they are severe, they pose a risk to the baby. You should consult your doctor.

As the body expands to accommodate the growing baby, the skin becomes lighter and stretch marks develop around the abdomen, thighs and buttocks. You will feel abdominal pains and backaches due to the weight of the baby. Your doctor may recommend support girdles to hold the weight of your abdomen and support your back. Use moisturizers to relieve itching associated with stretch marks. Do not worry because stretch marks fade away after pregnancy.

Tingling and burning sensations on the legs are common at night. Fluids collect in your lower limbs during the day and exert pressure on the nerves which cause tingling sensations or numbness. Massage and stretching the affected leg can help relieve the pain. You can elevate the affected leg when sleeping.


Nasal congestions, difficulty in breathing, nose bleeding and snoring are common. The gums may become softer and bleed when brushing your teeth. You may feel shortness of breath as your lungs try to meet your oxygen requirement and that of the baby. You will experience hypotension episodes accompanied by dizziness and hyperventilation. The depth of breath will deepen and the rate of breathing will increase. Due to increased oxygen demand, estrogen and progesterone dilates blood vessels. The result is that your blood pressure falls. Take lots of fluids to correct the low blood pressure and to control dizziness. These symptoms are usually minor and cause no need for panic unless you have underlying medical conditions such as asthma and bleeding problems. Severe dizziness may be a sign of anemia in pregnancy.

A thin acidic vaginal discharge is evident in the second trimester. It arrests the proliferation of fungi and bacteria which are harmful. Sometimes these microorganisms may evade the vaginal acidic medium and infest the vagina. Consult your doctor when you notice itching and greenish yellowish smelling discharge. Burning sensations when you pass out urine may be an indication of kidney or bladder infection. These pose threat to the baby.

The pregnancy hormones may cause difficulty in catching sleep at night. The remedies for this include exercising during the day. This will make you exhausted at night and induce sleep. Do not go to bed until your sleepy enough. Restrict intake of fluid at night to prevent frequent night urination. Avoid sleeping during the day as this will concentrate your sleep at night. You may try sleep inducing activities such as watching television, reading a novel or making love. Avoid stimulating beverages such as coffee and tea. They have caffeine which keeps you awake and is harmful to the baby.
