Fraternal twins one sac is much much smaller than the other!
So I had my 6-7 week ultrasound a week ago. Two sacs with two heartbeats, but you could barely see the second sac. What are the chances if we saw a heartbeat with both that both will survive? Could one sac just be behind the other and that is why it is hard to see the second easily?
I have uploaded the photo of my ultrasound pic
Just wondering how things have been going for you? I am in the same situation right now: 9 weeks with twins (both have great heartbeats though) and one sac is not even half the size of the other, although the babies themselves are only measuring about 4 mm difference. My OB told me there is a 50% chance of losing at least the smaller one and possibly both. This is our third pregnancy; the other 2 ended in early miscarriages so we are hoping and praying that our twins both make it!
My last ultrasound was on the 16th. They both had grown especially the smaller one, even though they are still different sizes. I have another ultrasound on April 6th then a level 2 ultrasound on the 15th to a specialist that will do a careful examination of the two of them. My OB never said anything about losing one of them but she still seemed a little cautious, that is why I have been going and doing ultrasounds every 2 weeks, and now it is 3 weeks, and then going to a specialist to make sure they are both doing good. It just seems weird that the second one hardly has space in the sac not much fluid around it while the first one has this huge swimming pool (lol). Being that I am 11 weeks I am a lot less worried now. I just can't wait though for my April 15th appt.
I hope everything is okay with your two. Please keep me updated on how your doing too. I honestly think that once the heartbeats are seen like I saw on mine and you on yours everything should be good ;)
Just wondering how your twins are? I am in the same situation with my sacs being 2 diffrent sizes, I wasnt worried, just thinking that the bigger sac is probably a girl and the smaller sac being my lil boy lol
Hi everyone, I'm also interested in how everything's going for you all.
I had a scan at 7w3d. Twin A measured 8.7mm (6w5d) and Twin B measured 7.4mm (6w3d), but twin B's sac was about half the size of the other and i've been told to be prepared that I might loose twin B. I wont get another US til 14 weeks. I'm currently 9weeks now and the wait and worry is driving me mad. Oh! and they're fraternal.
Hi. I know the odds of getting a reply to this is slim sonce this thread is almost a year old but I just thought it was worth a shot. Smilies 18 what was the outcome of your pregnancy? I just had an ultrasound and my images look very similar to yours. I am before heartbeat stage though. JUst wondering what my chances of keeping 2nd twin is. Doctor says 60%. Trying to stay positive
Hello ladies i am hoping to get a answer back but im not 7 weeks prego and have had the same issuse with baby b"s sac being smaller then baby a"s it is indeed like one of you ladies said baby b have like no space it seems and baby a has a swiming pool well they both have strong healthy heart beats and im hoping for the best trying to stay pos but they did say there could be a chance baby b stops growing i would like to know the out come of some of your twins THANKS
Hi I found out at 8 weeks im carrying twins..im now 14 weeks and went for my scan on the 10th twin 1 is quite abit smaller than twin 2..my consultant says not to worry as it may just be the pattern they both follow all the way through but I cant help but worry im bk for another scan in 3 weeks anyone else had the same problem at 14 weeks? X
At 5 weeks I knew there were 2 sacs but only one heartbeat was detectable. Today I went for another ultrasound. There were 2 heartbeats but dr said that twin b is not likely to survive until next u/s because it's considerably smaller and it probably had some chromosomal issues. I'm happy twin a is thriving but sad about the potential loss of twin b. could twin b's chances of survival improve and grow into a healthy baby?
