It is clinically possible to see a pregnancy sac on day 33 of pregnancy as it is usually visible under ultrasound around 35 days of menopause. If the pregnancy sac or germ can be seen on ultrasound, intrauterine pregnancy can be diagnosed.
For women who have regular menstrual periods and have a menstrual cycle of about 28 days, the gestational sac can be seen on most transvaginal ultrasounds on the 33rd day of pregnancy. For women with irregular periods, it is possible that the gestational sac may not be visible on day 33 of pregnancy, and it is recommended that a follow-up examination be performed a week later.
If the blood or urine HCG test result is positive on the 33rd day of pregnancy, but no gestational sac or germ is seen after ultrasound, the ultrasound may have been done too early, or it may be an ectopic pregnancy, which should be rechecked regularly without too much anxiety.
