yeah, so last week i was at my normal monthly dr visit, and i was measuring at 34.. 36 weeks so they scheduled me for a ultrasound... it went normal, i knew we were having a baby girl from our 1st ultrasound at 21 weeks. but they kept us after to talk to a dr she said she found a second smaller placenta. is that because there WAS twins?? or could it be that theres one hiding??? im still measuring big.. but with one baby!!

Possibly there was a twin. What did the doc say about it?

i havent really heard of such a thing before but here is what i got when i googled your question:
It is not common, but it happens. You probably conceived twins and one did not develop, it is called a blighted ovum. If you had conceived a single baby and it had not developed you would have had a miscarriage, but the healthy fetus is preventing this.
As the healthy baby grows the second placenta will probably be overtaken by the good one. An area of thickening may be found when you have your baby.
I have searched for the term "double placenta," and found that it is not a commonly accepted medical term because people don't agree what it means. Sometimes, a placenta appears to have two lobes. There is some speculation that some cases of what appears to be a double placenta is the result of the early loss of a twin.
To answer part of your question directly, in the case of monozygotic twins, there are three possibilities for the extraembryonic structures. With early twinning, there will be two chorions and two amnions; even in these cases, it appears that the two placentas fuse about half the time.
There are also cases with two amnions and one chorion, and finally, cases with one chorion and one amnion. Please see Figure 11.32 of Gilbert's Developmental Biology from the Books search at NCBI. Go to:
http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=Books
Search for "twinning" and find the figure from Gilbert.
Here is a report of a double placenta and bifurcated umbilical cord in a singleton pregnancy:

Finally, there is an excellent review on chimerism here:
http:// humrep.oxfordjournals.org/cgi/content/full/21/3/579
After reading this review, it seems to me that there is a great deal of dogma about twinning that cannot be correct.
I think that it is fair to summarize the possible causes of "double placenta" this way:
1) The placenta might appear to have two lobes in a singleton birth.
2) The "double placenta" might result from the early loss of a twin, or from the incomplete separation of twins in an apparent singleton birth of a chimeric individual.

Doesn't sound like twins nor a hiding baby. Just an EXTRA healthy womb. Everyone swore I was having twins, but I just had an 11 pound girl in there. Congrats and best wishes to you!

its the same as me this may not mean there are twins its because both placentas are feeding the baby thats why your baby may be big and why your doctor may be watching both placentas

They should be able to see if it is twins..ecspecially at 30 weeks. It could be there was a twin and it did not develop. I have heard of that happeneing. I would discuss this with the doctor at your next appointment.

A large number of pregnancies start out as multiples (pairs), but one is usually reabsorbed, so only one develops. It's quite common.

No, there is only one baby. The other placenta is an anomaly.
