No Yolk Sac

[DamionNW]

Hi. I recently found out I was pregnant about 3 weeks ago. About a week ago or so I started spotting bright red blood, so I went to the ER. They did blood work and my HCG was about 7000, so they said that placed me btw 51/2-7 weeks. They decided to do a transvaginal ultrasound to check the babys heartbeat. Upon doing the ultrasound I was later informed I was around 6 weeks along, they saw a gestational sac and a fetal pole that measured 0.33mm but no yolk sac. I haven't bled anymore since that day (but there was minor clotting) I was given a diagnosis of expecting to miscarry. I guess my only question is how is there a fetal pole if there is no yolk sac? Has anyone heard of this before? Any help would be greatly appreciated!

Thank you ma'am. I guess I haven't secretly given up hope. But considering the fact that they saw a fetal pole and measured my baby's crown rump I am worried that they are probably accurate in saying that I am 6 weeks....

a yolk sac forms between 5.5 to 6 weeks into the pregnancy. the yolk sac functions as a source of nourishment for the baby and eventually is actually absorbed by the baby as part of the 'gut'.

normally, when you have an ultrasound and there is no yolk sac there are two reasons for this. One reason is you have miscarried or will miscarry.

however, here is some good news for you.

this may also mean that you are not as far along as you think. if you are not at least 5.5 weeks pregnant this would explain why there is no yolk sac. it is very easy to be off by a week or so this early in your pregnancy as most women do not know the exact day they conceived.

The best thing to do right now, is wait. make sure you get another ultrasound and the outcome will either be a miscarriage or you will discover everything is normal and the doctor was off about how far along you are.

here is a website that has some good information about this.

Good luck!
