For those who have multiples -
To confirm they are ID or not, is it a simple blood test?
My girls had their own sacs and placentas, however as they are growing older, look MUCH more similar.
If we did want to TTC more children in the future, id be interested to know the chances of twins again, so want to confirm if they were indeed frat or not.

To confirm whether your twins are ID, you need to have a DNA test which involves a cheek swab and take a couple of weeks to process. A blood test can only tell you if they have the same blood type (if they are different then they are definitely fraternal, but if they are the same blood type, they can still be fraternal or identical).
The cheapest I have found is DNA solutions, I think it is about $160 for a twin zygosity DNA test.
I hope that helps.
