During intercourse, several hundred million sperm are released in the vagina.

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.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.At this stage, the menstrual period has just ended and your body is getting ready for ovulation.For most women, ovulation takes place about 11 – 21 days from the first day of the last menstrual period.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.

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.

Most references to pregnancy are usually in gestational age rather than fetal age development, but we have included both so that it is clear what stage development is being discussed.

A blood test can be used to monitor h CG levels and progesterone levels.

Ultrasounds can be used to visually see what development is taking place in the uterus and to measure the progress.

Within this time period, a yolk sac can be seen inside the gestational sac.
