From what I understand it can take 6 weeks before a sac is detectable on a vaginal ultrasound. If there is no sac at 6-7 weeks there is reason for concern.
No, by this stage the fetus should be clearly visible. The yolk sac is visible from 5 weeks.
iam 5 weeks pregnant sac is not seen but bleeding
You wouldn't normally see a sac on ultrasound until about 5 weeks. Sounds normal.
If you are 7 weeks from your last period, you are seven weeks pregnant, 3 weeks pregnant is before you miss a period and you would not have a scan then. If you are seven weeks and there is no sign of a fetal pole it appears that the embryo may not have developed and you will miscarry soon, I am sorry.
nothing every child grows at a different rate at a different time no worries with in a week is not a big deal
No the embryo is well protected.
You shouldn't be big at all. At five weeks pregnant you have just developed an embryo. An ultrasound typically will not even be able to detect a heartbeat yet.
There are two answers to this - one good and one bad. The most probable answer is that you miscalculated and you are actually 5 weeks pregnant. Unfortunately there is a possibility that you did fall pregnant 9 weeks ago and that the pregnancy will not progress. It is possible that either the fetus is not developing, or that the fetus has died which usually means the gestational sac will shrink and appear to be not as advanced as you are.
first..make sure what you're asking makes since.
At around 4 weeks of gestation, a developing embryo may not be clearly visible on an ultrasound. Typically, a gestational sac can be seen, but the embryo itself may not be identifiable until about 5 to 6 weeks. The visibility can vary depending on factors such as the type of ultrasound used and the individual characteristics of the pregnancy.
You are correct. A yolk sac is typically visible on ultrasound around 5-6 weeks of pregnancy, which is dated from the first day of the last menstrual period. Therefore, if the yolk sac was measured on January 7th, conception would have occurred prior to January 4th.
Typically, a gestational sac can be seen on an ultrasound around 4 to 5 weeks of pregnancy. However, it may take until about 6 weeks for a healthcare provider to reliably see the developing embryo within the sac. If you are seeing an empty sac at this stage, it might just be too early, and follow-up ultrasounds are often recommended to monitor the situation. Always consult your healthcare provider for personalized guidance.
