Hey Ladies, Knowing about your Pregnancy Stage Per Trimester

Pregnancy Stage per trimester

Pregnancy Stage per Trimester - The nine months of pregnancy, from conception to birth are an exciting time of change. As the embryo grows and develops into a baby, many changes are also taking place in the mother's body. So in order to easily understand these changes the whole pregnancy is divided into three trimesters which comprises of three months each.

First trimester:

This stage comprises the period from conception to 12 weeks of pregnancy (or) 14 weeks from the first day of the last menstrual period. Some women find it very difficult to pass through this period as everything is so different, so exciting, so overwhelming all at once. There will be an amazing development of the baby in this stage.

Conception to embryo development:

A healthy first trimester is crucial to the normal development of the fetus. The mother-to-be may not be showing many changes on the outside, but inside her body, all the major body organs and systems of the fetus are in the formative stage.

The male sperm and female ovum fuses around the day of ovulation and a zygote are formed. It undergoes rapid division, leading to the formation of an embryo. The embryo gets implanted in the uterine wall (5-7 days after fertilization). After that, several developments take place.

A sac filled with amniotic fluid, called the amniotic sac, surrounds the fetus throughout the pregnancy. The placenta grows only during pregnancy. It attaches to the uterine wall with tiny projections called villi. Fetal blood vessels grow from the umbilical cord into these villi, exchanging nourishment and waste products with the mother's blood.

  1. The embryo develops a spinal cord. Three germ layers are seen which divides rapidly to form the different organs.
  2. Limb buds appear which later develops into arms and legs.
  3. By the second month, the growth of the fetus is enormous. At the end of this month, major body organs, and systems are formed.

Changes In The Mother:

During pregnancy, mother undergoes lots of changes in her body both physically and mentally. But these changes do not exist together in all the mothers. Some people will have minimal symptoms, some will have exaggerated symptoms.

Some of the common changes that all the women's experiences are:

  1. Breast feeling tender, sore and enlarged. The areola surrounding the nipple gets darkened. The veins on the surface of the breasts become prominent.
  2. The enlarging uterus pushing against the bladder and the hormonal influence has made the pregnant women urinate often.
  3. Constipation, indigestion also can be seen.
  4. Morning sickness with vomiting sensation on the sight of food due to rise in the hormone levels, especially in the morning but may found throughout the day. But pregnant women despite this feeling should try taking essential nutrients.
  5. Increased craving for some strange food like pickles, raw mango etc.
  6. Fatigue, dizziness, headache---due to raised progesterone (hormonal effects) compounded by increased blood volume, which leads to falling in blood pressure and fall in blood sugar hence leading to the deficient blood supply to the brain. This is also due to increasing metabolic needs of pregnancy.
  7. Mood swings, dysphoric effects, depressed mindset due to the effect of progesterone on the mood regulatory part of the brain.

There are increased chances of miscarriages in this stage as the fetus is susceptible any abnormal changes or substances.
