Hello
Thanks for posting your query at DoctorSpring.com
Just one single image cannot help me decide whether the twins are fraternal or identical.
I need to have the report of the ultrasound scan.
Please upload that.
Looking forward to hearing from you.
Take care.
Regards.

These are the only photos I have. I don't have very good communication with the woman so I'm not sure if I could get the whole report. She told me they were fraternal twins but in order for that each embryo needs their own placenta correct? These photos only show one placenta. Here are the two photos I have. I know you probably can't tell me 100% for sure, but could you give me some idea? Thanks

If they were fraternal, they generally have two separate placentas.
At times, they might share a placenta again.
The diagnosis of identical twins requires much more information.
yes, if the placentas are separate, they are definitely not identical, but not the other way round.
The two photos give no information, I cannot even say that the placenta is single.
Ultrasound is 3 dimensional, it is like taking a flat photograph of the globe and then trying to comment on it.
Hope you understand.
Try and procure the report, I would then be able to help you.
Take care.

Hello Dr Vazirani,
We did an ultrasound today. They are Monochorionic-Diamnotic twins. What health risks should we look for? She has another appointment on April 20th, should we get one sooner? The technician said the babies are healthy but they are identical twins.

Also, the ultrasound said she is at 14 weeks. We concieved on New Years which would date them at 11 weeks and 2 days. Is this normal? Is there a possibility they could not be mine?

Thank you
Mitchell


Hi again.
So, they are identical twins.
Well, complication risks are higher with monozygotic ( identical twins ).
15 - 30 % risks of developing inter twin blood flow complications resulting in deviant growth / demise of one / both babies.
Other health risks common to all twin pregnancies - excessive weight gain, maternal hypertension, maternal diabetes, preterm labour, preterm babies, risk of excessive bleeding during labour and postpartum period, malpresentation, increased risk of Cesarean birth etc.
Please go through this link, it will help -

Regarding paternity, I need more details please -
Date of her last menstrual period.
Were her cycles regular?
Date of sexual intercourse?
Dates of all scans done so far with the reports ( if not images.)
Without that, I would not venture to speculate on paternity.
Take care.
