What happens during gestation?
In the first few weeks following conception, your hormone levels change significantly.
Your uterus begins to support the growth of the placenta and the fetus, your body adds to its blood supply to carry oxygen and nutrients to the developing baby, and your heart rate increases.
What does early gestation mean?
The gestation period is how long a woman is pregnant. Most babies are born between 38 and 42 weeks of gestation. Babies born before 37 weeks are considered premature.
What is gestational age and fetal age?
The following information is used as a general guide for healthy pregnancy development, although development may vary due to the mother’s health or a miscalculation of ovulation. Gestational age is the age of the pregnancy from the last normal menstrual period (LMP), and fetal age is the actual age of the growing baby.
Which trimester is the most critical?
Pregnancy The Three Trimesters
- First Trimester (0 to 13 Weeks) The first trimester is the most crucial to your baby’s development.
- Second Trimester (14 to 26 Weeks) The second trimester of pregnancy is often called the “golden period” because many of the unpleasant effects of early pregnancy disappear.
- Third Trimester (27 to 40 Weeks)
How does a baby form from sperm?
Sperm begin developing in the testicles, the two glands in the scrotal sac beneath the penis. The sex of the resulting embryo depends on which type of sperm burrows into the egg first. Sperm with a Y chromosome make a boy baby, and sperm with an X chromosome make a girl.
What does 7 weeks mean?
Late Term. > 42 0/7. Postterm. Using the LMP (last menstrual period) method, a full-term human pregnancy is considered to be 40 weeks (280 days), though pregnancy lengths between 38 and 42 weeks are considered normal. A fetus born prior to the 37th week of gestation is considered to be preterm.
How is gestation calculated?
In cases where the date of conception is known precisely, such as with in vitro fertilization, the EDD is calculated by adding 266 days to the date of conception. Ultrasound uses the size of the fetus to determine the gestational age (the time elapsed since the the first day of the last menstrual period).
How do I calculate my gestation period?
Gestational Age by LMP is calculated from the first day of the last menstrual period. EDD by LMP is calculated by adding 280 days (40 weeks) to the first day of the last menstrual period. Gestational Age by US is measured by ultrasound (US) on the Ultrasound Date.

Why do doctors add two weeks to pregnancy?
Your due date is based on your last menstrual period, so that would put it about two weeks off from your conception date. While pregnancy is actually 9 1/2 months, doctors calculate it as 10 months because they add those two weeks in before conception. Hope this helps you! Congratulations!
