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.
During my sister's first pregnancy, she went to the hospital bc she had an mc. But it wasn't until then that she found out she was pg with twins and only lost one of them! Turns out she ovulates two eggs each month and there is a good chance she could get preg with twins every time.
