You will likely see the gestational sac and maybe the yolk sac.
It is possible to see a uterine sac, called a pseudo sac, with an ectopic pregnancy, but most likely there will be nothing in the uterus.
You should be able to see the yolk sac at 5 weeks.
Sac spiders or Clubionidae live all over the world.
at about 4 weeks they can sometimes see the gestation sac. by 5 weeks they can usually see the yolk sac. and by 6 weeks you can usually see a fetal pole, sometimes even a heartbeat
From just over 5 weeks, see the associated website I had my first u/s done at less than five weeks I was probably 4.4 weeks, but all I showed was the yolk sac and the sac....no fetal pole or baby. == an internal ultrasound can detect a pregnancy much sooner than an external ultrasound, even if all it detects is a yolk sac.....there would not be a yolk sac if you were not pregnant.
Yes At this point you SHOULD see that.
Yes.
Yes, yellow sac spiders are found in all but the most northern states in the U.S.
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.
sac-like
Don't stress out! With my 2nd baby I had the same thing. I was convinced that I was going to miscarry. I had another ultrasound at 6 weeks and at that time all they saw was the sac, then finnaly at 8 weeks we got to see that little peanut.
