Sometimes, a small sample of tissue may be taken with small tools inserted through the vagina during a transvaginal ultrasound. In all three types of pelvic ultrasound, the transducer sends the reflected sound waves to a computer, which makes them into a picture that is shown on a video screen.
Before birth, a fetus starts with around 2 million eggs in each ovary. Those eggs are trimmed down over time, and a girl is born with around 300,000 eggs in each ovary. She â¦normally releases 1 egg a month during her fertile years.
Which ovary produces the egg each month is random. It is usually a short-lived discomfort and is best ignored if possible. As far as the clots go, the size of these really depends on the rate of blood loss from the lining of the uterus, which is shed during a period and is the cause of the bleeding.
