Difference Between Ultrasound and Viability Scan?


Hi Ladies! Can anyone tell me the difference between a transvaginal ultrasound and a fetal viability scan? I went to my OB today (I should be 6 weeks 2 days along) and I am really worried. I have a healthy 16 year old but in 2005 I had a blighted ovum. That was a horror story, as after they did the removal I had a SECOND D&C within 4 days where the doctor said he was removing "fetal matter". Well - if there was no fetus to begin with, there shouldn't have been an emergency 4 days later right? Anyway - I went for my 1st checkup as I am very high risk. Doc saw the sac but said it is much to early to see a fetus and is sending me for a viability scan. What on earth is the difference? I can't seem to find anything online at all and am freaking out at seeing an empty sac again.
I did just have surgery in mid April and I thought my LMP was 4/20 but it may have been 4/24 which puts me just a few days behind. I also know with those dates I conceived on 5/4 or 5/8 and I know that it can actually take a few days after to truly conceive so I may have had implantation on says 5/6 or 5/7 or of 5/8 was the day it could have been 5/9 or 5/10. So.. Please let me know if you know the difference between a trans-vag us and a viability scan. Thank you SO much!

hi hun
a viability scan is used to check a prgnancy is developing normally (is viable). it can be done transabdominally like a normal ultra sound after about 7 weeks. before this it will be done vaginally. before 7 weeks all they will look for is that the sac is in the uterus as they are unlikely to see a heartbeat. between 7-11 weeks the embryo(s) and heart beat(s) can often be seen and the pregnancy can be approximately dated. hope this helps xx

Thank you Ashlee! I am so worried! This is crazy - they did see the womb but nothing in it with the transvaginal. Now I have a little blood mixed in with my discharge (Doc said I might since they did a pelvic). I just want a normal pregnancy! My 16 year old was 2.5 months early then that horrible blighted ovum 6 years ago
I would have thought they would have at least seen a yolk sac on the transvaginal ultrasound today?

The problem with the transvaginal is that if they cant get a clear picture of the uterus they would usually us saline infusion sonography, this cant be used on pregnant women and with you being so early on (Im assuming from your dates your very similar to me, around 6 weeks) it may be difficult to confirm viability but baby should be growing quickly this week.
Pelvic can cause slight bleeding and its often nothing (Have been asking a friend who is also a tutor in the midwifery department at my university for this info)
Really feel for you with everything you have gone through and hope you get some reassurance from your scan. Get the feeling from this forum though a normal pregnancy involves being terrified half the time though. Hope everything goes well this time xx

Thanks again Ashlee. I don't know what to make of it all. The doctor looked like she was getting excited and began to flip the screen toward me then moved it away then once again she looked excited and moved it away, which makes me think perhaps she saw something, which is by far better than nothing. I am just soooo worried- when I saw the printouts, yeah only for a brief moment, it just looked like a big black empty womb like my blighted ovum. The doctor did say she didn't expect to see anything, so I don't know. Perhaps I am just paranoid with this, but I almost feel as if "I know" I am having the same problem as before. And, with a blighted ovum there are no symptoms - you just go in and find there is no baby. I really hope that when she had the look of excitement on her face she was seeing something and that's why she was going to show me. She also said "I am not concerned right now", so I just don't know. Thursday is the viability scan and I do hope they see something. But ever since my pap yesterday I am having constant cramps like period cramps, boobs hurt far less, no sickness (but I do get that every other day). I think I need to prepare for the worst and hope for the best. Hope that implantation was several days off, as that too could explain why there was not even a flicker. This pregnancy was a real surprise but a very welcome one by me, something I have wanted for a long time but hubby wasn't going for. If I have lost this one, I know it won't happen again
Best of luck to you in your pregnancy and I hope Thursday I can give you good news. Strangely I am a very optimistic person and in this situation I am very down and pessimistic. Totally awesome you have a friend with so much knowledge that you can talk to because I do agree, these boards scare the crap out of people! Thanks so much for writing to me!

Hey Ashlee! Just wanted to tell you I went for the viability scan (scared to death laying there) and wow - saw the little heartbeat at 110 bpm! Just a little lima bean in there with a heart thumping away. Found out I was only 5 weeks 5 days yesterday so holy moly! I must have been way off on my calculation! I thought I was going on 7 weeks or more now! That would explain not seeing anything on the first u/s definitely!

So glad for you! Keep in mind your dates might still be right. At 6+3 I was measuring 5+4 and somewhere along there it caught up! I too had an empty sac at 5+4 and was worried it was a blighted ovum, but I guess it was just taking its time. These early scans are awful!!!! I wish I hadn't gotten one til 7 weeks. It gave me so much worry!!!
