What is a pregnancy trimester ?


first trimester

Pregnancy is divided into three trimesters (each trimester into 3 months) and then broken down into weeks (each trimester is slightly longer than 13 weeks). A full term pregnancy is counted 40 weeks and any pregnancy delivered before the 37th week is considered to be premature. Pregnancy is counted from the first day of your LMP (last menstrual period). That means by the time of conception, you are considered to be two weeks pregnant.

Pregnancy is calculated using gestational age, starts on the first day of your LMP (Last Menstrual Period).

Most of the women think that pregnancy lasts for about 9 months, it is true, but, as the pregnancy is calculated from her LMP that is about 3-4 weeks actually she is pregnant – a full term pregnancy takes about 40 weeks from her last menstrual period (that is approximately 10 months).

The sure way to measure the gestational age is with an ultrasound scan.

First trimester – week 4 through 13 weeks:

The first, second, and third month of pregnancy are called the First Trimester Pregnancy. Stopping your period is a clear indication that you are pregnant. By the end of the first trimester, your baby is around 3 ½ inches long. The amniotic sac contains about 3.5 ounces of amniotic fluid and the fetus has ample room to move, but the movements are yet not felt by the mother. The amniotic fluid is refreshed constantly by the amniotic sac.

Your first trimester pregnancy symptoms may include:

  • Tender and swollen breasts with your nipples sticking out.
  • Extreme tiredness
  • Upset stomach with or without morning sickness.
  • Cravings or aversion for some foods.
  • Mood swings
  • You will have trouble with bowel movements (Constipation)
  • Headaches, heart burn, indigestion.
  • Frequent urination (the urge to pee).

You may need to change your daily routine as your body changes. That can be eating small frequent meals or going to bed early. Some people will not have any discomforts at all and for some it continues till delivery and for some it goes away as the pregnancy progresses. Each woman is different and so is each pregnancy.
