Morning sickness
About 70% to 80% of women may experience morning sickness with symptoms such as nausea and vomiting in the first trimester of pregnancy, because of increased pregnancy hormones.
A small percentage of women may experience morning sickness in the 2nd trimester, and occasionally, it continues throughout their entire pregnancy.

In fact, this condition can strike at any time as nature’s way of protecting the mother and the foetus from food-borne illnesses and chemicals.

Your 1st trimester milestones
- At early three weeks from the first day of your last period. The fertilised egg moves slowly along your fallopian tube towards your uterus. It begins as one single cell, which divides again and again. By the time the fertilised egg reaches your uterus, it has become a mass of over 100 cells, called an embryo. It is still growing. Once in your uterus, the embryo attaches itself into your uterus lining. This is called implantation.
- Just 12 weeks after conception. Your baby has all of their organs, muscles, limbs and bones, and their sex organs are developed. Your baby is already moving about, but you will not be able to feel movements yet.
Baby’s 1st trimester progress

Braxton Hicks contractions
Your uterus might start contracting to build strength for the big job ahead. You might feel these “warm-ups”, called Braxton Hicks Contractions, in your abdomen. They’re usually weak and come and go unpredictably. Contact your health care provider if the contractions become painful or regular. This could be a sign of preterm labor.
Skin changes
Hormonal changes during pregnancy stimulate an increase in pigment-bearing cells (melanin) in your skin. As a result, you might notice dark patches on your face.

Stretch marks
You might notice pink, red or purple streaks along your abdomen, breasts, buttocks or thighs during the second trimester of pregnancy.

Increased blood circulation can also soften your gums, which might cause minor bleeding when you brush or floss your teeth. Switching to a softer Toothbrush can help decrease irritation.

Pregnancy causes your blood vessels to dilate and your blood pressure to drop, which might leave you dizzy. If you’re having trouble with dizziness, drink plenty of fluids and rise slowly after lying or sitting down. When you feel dizzy, lie down on your left side to restore your blood pressure.
Leg cramps
Leg cramps are common as pregnancy progresses, often striking at night. To help prevent leg cramps during pregnancy, stretch your calf muscles before bed.
