Looks like the umbilical cord hun definitely not another baby. Looks like one helthy singleton. Not to mention they would have definitely noticed by now.

I vote that is just umbilical cord! 

I've never realized how many doctors and ultrasound techs use this app! This is phenomenal!!! To have such professional opinions about every medical related post (without them having a proper title or degree) is so nice!

Next appointment show them and ask about it! Sometimes twins go undetected because one will hide, happened to a friend of mine! Good luck and congratulations hope you have a happy healthy nine months! 

Yeah that for sure don't look like another baby lol and having 4 sonograms they would of detected it

Doesn't look like another baby 

It might look like the shape of a face, but that doesn't mean there's a baby there. 

Nope - just one

I think they would have told you by now!! I mean there would typically be a second heartbeat heard! And your hcg would have probably been higher and what not... you can mention it to your dr but im almost positive they would have said something to you by now! Alot of times twin pregnancies are classified as high risk it would be pretty irresponsible and unprofessional for them to just not mention it!

Not a twin.
