Have you had a hidden twin on ultrasound

Is it true that sometimes a twin can be hidden on an ultrasound as far as 8 weeks? I am kinda nervous. I just had twins last February (10th) so my twins will be 1 year old tomorrow. They are fraternal so I knew the risk of conceiving twins again. I am now 3 months pregnant with an "oops" baby. Unplanned but I am excited now. This one is due when my twins will be 18 months.



My doctor did an ultrasound at 8 weeks and said he only "saw 1 but we would know for sure by 12 weeks." 12 weeks is tomorrow morning. If it's twins I will love them both as if I had purposed to conceive them both but obviously I am nervous about how difficult it could be. The ultra sound looked very clearly like ONLY one and when I had my twins, we had an ultra sound at ten weeks and they were very distinct and separate. I don't see how it could be possible to have a hidden twin.



Has it ever happened to someone where you did not see the second one at 8 weeks but then saw it at 12? Please calm my fears on this hidden twin situation. I know it is just bc tomorrow is my ultra sound and all of a sudden it hits me that "what if they DO see another one?" you know? what if i have a hidden twin? Please tell me if you have had an 8 weeker hidden twin you didn't know about until later on in the pregnancy.

I am pregnant for the third time I have 1 two year old son and I had a miscarriage the 16th of March and now I'm pregnant again. I have had this strong feeling I'm pregnant with twins. At 4 weeks my hcg level was 587 and I'm already showing. They thought that I was 7 weeks 1 day along and today when I had an ultrasound they changed that to only 6 weeks 1 day. They said they only seen 1 baby on the ultrasound but I still have a feeling there is two. Twins run on my moms side of the family.

Does anyone have any thoughts on whether or not I could have a hidden twin?

IIs it.common for you to have one ultrasound and it show twins clear as day and the next time only show one, the second one hiding. I'm 12weeks and three days ago the doctor did an ultrasound sound two babys clear as day in two different sacs, and today I had the ultrasound for disorders testing and she only saw one baby, I'm co.fused she said to.go with the doctos.ultrasound. has.anyone experiences anything like this.

Yes. I went to the (highly respected) Dr. at top facility when I was about 6 weeks 6 days. The Dr. stated "there is definitely only one in there." We saw one baby. We heard one heartbeat. Because I had a previous miscarriage and over 35, she wanted to see me a few weeks later. I went in at 9 weeks, 6 days (early Nov.'11). This time she said "there are definitely two babies in there --identical." Hubby and I were shocked but happy. It still happens today.

I was told i was only having 1 baby at my 6,12 and 18 week scan, but i was huge so i pleeded with my doctor for another scan and he said no there is only one baby i said it must be going to be a really big baby, he it was of average size so i asked him if he could tell me what the sex was and he said its a boy then he said hang on no its a girl i was really confused, he left to go and get someone else to look at scan and it was only then that they discovered i was having twins! a boy and a girl!! she was a bit smaller than him and tucked right in behind him, to this day i am always searching for her she just loves to play hid and seek..

I'm 4 months pregnant and i look like I'm 9 months pregnant. I'm exhausted and all I do on my days off is sleep.... This is unlike my other 3 pregnancies. I swear there has to be twins or more in there, but the US only showed 1 baby.

Was just looking back at this post and just wanted to annouce that I DID indeed have only 1 baby and she is my perfectly healthy now 20 month old Annabelle Jayde! The twins just turned 3 in February so they are exactly 18months apart and all get along GREAT together so for the comments above about how far apart to have kids, I think it ended up working great. Honestly, I have not found it any harder than I can imagine only the twins being. (She was a 9 pounder too at 1 week early-drastically different than my 6 pounder twins!) Anyways, it was just interesting looking back at this comment and remembering my feelings (fears) at first finding out about being pregnant with her! I cannot imagine my life without my little BelleBelle!

Danielle, I never had HCG levels done with any of my three pregnancies, although I would like to know what it was with my twins. They were pregnancy # 4 ( 1 miscarriage) and I was showing at 8 weeks with them. I have two friends with twins that were missed on early ultrasounds. First friend had her scan at 7 weeks, and they said one baby, then they saw her twins at the 12 week scan. Second friend didn't know it was twins until 22 weeks. She went on to have them at 25 weeks so she didn't have long to get used to the idea! Time will tell if you're having twins or not.

Michelle, my twins just turned 1 two weeks ago (February 10th) and I am 3 1/2 months pregnant. Was freaked out when i first found out about this little #3 but now I am ecstatic! Can't tell you how hard/easy yet but I can tell you that My sister has 3 babies under 2 1/2 (no twins) and she loves it! I figured if she can do that then mine won't be impossible! When you are ready you will know! GL!

Hi, I'm glad you have been reassured that it's one! I am thinking of having more now (mine are nearly 3 years old) but a little nervous it may be twins again. I love having twins, but one would be nice next time!!!! I found out I was having twins at 7.5 weeks as I had HG (severe sickness) and they were both clearly vissable. I was told at 16 weeks that I had lost one of them-I hadn't-one was hiding as he was quite high up (my twins were transverse and one above the other, not side by side).

Well, I just had my 13 week ultrasound last week and indeed there is only one!!!!!!! That's 3 ultrasound's now (1 at 7 weeks, 1 at 8 weeks and 1 at 13 weeks) so I am CERTAIN we are only having one! (Praise Jesus!) (not that a second set wouldn't be great...but you all understand I am sure!) :) thank you everyone for your comments/input on the hidden twin ultrasound topic!

Yes it is true at 7 weeks I was told there might be twins but I had to come back at 9 weeks to make sure. Well, at 9 weeks they were totally sure it was twins the two sacs were very visable, but when they told me at 7 weeks that one might be hidding I kind of knew they was two. Good luck and enjoy

When I was 13 weeks pregnant I finally got to see a doctor (military insurance!) When I went in the first thing I said was "please check for two heartbeats." Because my entire life I'd always wanted twins. Well the doctor (if that's what you want to call him) said he only heard one. I did my bloodwork to check for diseases in the babies and the test for Spina Bifida came back elevated. So of course I was freaking out and preparing for a baby with a handicap. When I got to see the doctor again it was a week later, and he did an ultrasound in which he only saw one baby. Two days later I went to go see an ultrasound tech to have her check me out, and the first thing she screamed was "I DON'T KNOW HOW HE DIDN'T SEE THIS!" It was very clear on the screen two little heads. Needless to say I dropped that doctor!!! And now I have my beautiful 11 month old boy and girl.

I had an external and an intrauterine ultra sound at 7 weeks & 2 days due to bleeding. I asked if there were twins...just a strange hunch. The tech said no and she had looked very carefully because I had asked (my dad is a twin, my great-grandma was a twin, dh's dad is a twin and I was in my 30's & alread had 4 kids which increased the likelihood I might have twins). So I got bigger & bigger. At around 4.5 months I had another ultrasound to make sure the placenta had healed back onto the uterus. It had and that is when we discovered there WERE hidden twins. My twins are now 9!!

I had my first (vaginal) ultra sound at 6 weeks and they could very clearly see two sacs... Was your first ultra sound an abdominal or vaginal?

It can happen. My sister had a baby a few years ago, and they could hear two heartbeats (obviously different) throughout the whole pregnancy. Both were quite fast and similar, but not an echo. They couldn't see two babies though, only one. They did several extra ultrasounds trying to find the other baby, and up until the day she delivered said that although they thought there were two, they weren't sure, and it was very possible one was just overlapping the other perfectly the entire time. She ended up having one baby, and the extra heartbeat was hers! We have genetic tachycardia the doctor forgot about so heart rate is quite fast, and even faster when pregnant (180s).
