Since every woman’s menstrual cycle is different, the ultrasound presentation at 40 days of pregnancy will vary. For women with an early menstrual cycle, the ultrasound usually shows the presence of a visible gestational sac in the uterine cavity at 40 days of pregnancy. There is also a yolk sac within the gestational sac and even a fetal heart and buds growing. If a woman’s menstrual cycle is not regular, the ultrasound may not show a visible gestational sac in the uterine cavity, but simply a thickening of the uterine lining. Therefore, it is recommended that women should have an ultrasound around 50 days after menopause to confirm the diagnosis of intrauterine pregnancy and to look at the fetal heart and buds. For women who do not want to have children, it is often necessary to terminate the pregnancy as soon as possible with an abortion.
