Weeks 1 & 2 – Gestational Age
** 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.
The menstrual period has just ended and your body is getting ready for ovulation. For most women, ovulation takes place about 11 - 19 days from the first day of the last period. During intercourse, several hundred million sperm are released in the vagina. Sperm will travel through the cervix and into the fallopian tube. If conception takes place, the sperm will penetrate an egg and create a single set of 46 chromosomes called a zygote - the basis for a new human being. The fertilized egg spends a couple days traveling through the fallopian tube toward the uterus, dividing into cells and is called a morula. The morula becomes blastocysts and will eventually end up in the uterus. Anywhere from day 6 - 10 since conception, the blastocysts will imbed into the uterine lining and begin the embryonic stage.
