h CG can be detected through two different types of blood tests, or through a urine test.

A quantitative blood test measures the exact amount of h CG in the blood, and a qualitative h CG blood test simply detects the presence of h CG.

Development The earliest change that can be seen through a vaginal ultrasound at this time will be the “decidual reaction,” which is the thickening of the endometrium.

This early part of development lays the foundation for a healthy pregnancy and delivery.

If a possible complication in early pregnancy is suspected, your health care provider will use a combination of blood tests and ultrasound tests to make a clear diagnosis.

The corpus luteum will produce progesterone for about 12-16 days (the luteal phase of your cycle.) When the egg is fertilized, the corpus luteum will continue to produce progesterone for the developing pregnancy until the placenta takes over around week 10.

Progesterone is the hormone that helps maintain the pregnancy until birth.

Sometimes, the failure of the corpus luteum to adequately support the pregnancy with progesterone can result in an early pregnancy loss.

Progesterone inhibits immune responses, decreases prostaglandins, and prevents the onset of uterine contractions.

The morula becomes a blastocyst and will eventually end up in the uterus.

Anywhere from day 6 – 12 after conception, the blastocyst will imbed into the uterine lining and begin the embryonic stage.

It is common to have many questions about what this early development truly involves and what is to be expected.
