Can I see the gestational sac after 40 days of amenorrhea?

Vaginal ultrasound is the general name for intravaginal B-ultrasound, which is a method of ultrasonic diagnosis by inserting a B-ultrasound camera into the vagina. Vaginal ultrasound has become the key method of prenatal examination today. Compared with abdominal B-ultrasound, the images of vaginal ultrasound are more realistic and accurate. More importantly, women don't need to hold their urine during the test. So, can the fetal sac be seen 40 days after menstruation?

Can the fetal sac be seen after 40 days of amenorrhea?

In the case of amenorrhea for 40 days, the first thing to look at is the patient's menstrual cycle. If the menstrual cycle is usually every 28 days, or even earlier, the gestational sac can be seen 40 days after menstruation. Of course, a vaginal B-ultrasound examination should be done at this time, because vaginal B-ultrasound will be more accurate than abdominal B-ultrasound. If the patient's menstrual cycle is relatively long, exceeding 30 days, or even 40 days, the gestational sac cannot be seen under B-ultrasound at this time. This is because after the menstrual cycle is prolonged, the time of egg fertilization is delayed. Therefore, in this case, it takes about a week to see the gestational sac under B-ultrasound. If you can't see it, you can do a blood test to dynamically observe the changes in HCG, which can also help you understand whether the baby is growing and developing normally.

How can I see the fetal sac during vaginal ultrasound at 40 days?

1. Under normal circumstances, an early pregnancy test is done about 35 days after the menstruation stops. The echo of the fetal sac can be seen under ultrasound 40 days after the menstruation stops. It is recommended to return for ultrasound one week later to clarify the situation.

2. The gestational sac can usually be detected by B-ultrasound examination 5-7 weeks after pregnancy. It is recommended to do an ultrasound examination 6 weeks after menstruation to confirm intrauterine pregnancy.

3. I am 40 days pregnant. I saw the gestational sac during transvaginal ultrasound, but I cannot confirm whether the gestational sac is growing in the uterus. If you don't see the gestational sac during abdominal color ultrasound, it means that you have menstrual disorders, or the pregnancy time is less than 40 days, or the test tube embryo is incompletely developed. It is recommended to wait 7-10 days before re-examination.
