No yolk sac but fetal heartbeat

[wonderme]

I posted this in Women's Issues, but saw someone mention the expertise here, so I'm reposting.  I would appreciate any comments.


Hello all. I have a question -- can you have a fetal heartbeat (even a slow one) without having a fetal yolk sac?

I keep reading about having the yolk sac but not having a fetal heartbeat...but can it be the other way around?

Has anyone heard of this?

My first US had a slow fetal heartbeat -- didn't tell me until I questioned them later that they did not (could not?) find a fetal yolk sac. Seems that is the first to develop (before HB) so if it never did then how can you get a heartbeat.

Any help is appreciated.

Thank you.

How far along are you?  I had u/s at 5, 6, 7, & 8 weeks and was upset b/c each time we saw different things until the 8 week, when we saw yolk, h/b, etc.  I'd ask to go back in 5-10 days for another. How are your HCG numbers & prog?

no yolk sac no baby.  the yolk sac is what makes the pregnancy progress w/o the baby can't sustain itself.  it must of been hiding. ultrasounds are tricky..

I agree with 5preg2b, it must be hiding ...you are so early.  I wouldn't worry....depending on how far along you are there have been several posts at seeing this and that at this stage....but not this...

I say around 8-9 weeks is the best time to get an u/s ....they usually can see everything at that point.

MANY PRAYERS FOR A HEALTHY AND HAPPY PREGNANCY

M y fiancee and I are having the  samre issue.  When we first found out we were pregnant the doctor figured we were about 4 weeks along alreasdy 6 .  My fiancee had missed 2 periods, and this is what the doctor was e doctor figured based on the information.  But My fiancee also will sometimes miss a period because of stress.

Anywho....she went to the ER today because of cramps, they did a vaginal ultrasound and could not find the yolk sac, but there is a baby that looks about 6 weeks and there is a heartbeat of 150bpm.  so we are thinking that the doctors initial guesimation on when we got pregnant was incorrect, 6 weeks make a little more sense to us, but regardless we are still really worried.  We have another apointment tomorrow at a better hospital with better equiptment, so we are praying for the best, that maybe the baby is just "hiding"  

Thanks for listening, it is nice to know that there are groups out there.

It is my understanding that the heart forms from the yolk sack, so no yolk sack, no heart beat.  I watched this on "building babies" on the discovery health channel.  Maybe you could order this video... it is amazing seeing the stages of development.

Your little guys heartbeat is VERY strong that early.  I wouldn't worry about a thing.  At 8w2d my baby's heartbeat was 167.7

I promise you this is possible because it happened to me..I had no yolk sac but my fetus had a heartbeat at 6wk3days of 124bpm. 2 days later it died. So, it is possible because it happened to me but my Dr. said it is very rare..like I have a better chance of being hit by lightening than what happened happening..but I know now any absence of yolk sac is a bad sign even if you do have a heartbeat. Hope this helps.

hi it is true about the fetal heartbeat with no yok sac. i was eight weeks pregnant and i started spotting. i was sent for a ultrasound scan and they siad that there was a fetal heartbeat there but cannot find the yolk sac. i was called back four days later  for a rescan and the baby had died. the midwife said without a yolk sac the baby wouldnt really be able to survive without it. this is my second miscarraige this year now. frightened to try again, but the only hope is that i have a seven year old daughter, so i know i can have children. the midwife said i have to have three miscarraiges on the run to be tested why. hope this helps you. good luck.
