One of the PPs is right....they could still be identical. The only way you can tell fraternal vs. identical is if they share one or both sacs...and that's the only way to determine for sure identical. There is no way to determine, for sure, fraternal (unless of course they're opposite genders).
My cousin was told she was having fraternal twins because of the separate sacs. Her boys couldn't BE more identical in looks
s. I was upset about being pregnant with twins--they were unplanned, and I went through long stages of being upset, resentful, and completely overwhelmed. I also wanted to find the "reason" this had happened to me. That's normal and it's completely okay. Ride it out, feel what you need to feel, and in the end you'll be in a healthier emotional place to become a mom.
If it helps, by the time they were born I was happy and excited to be a mom. The first few months were overhwleming, for sure, but you survive that and go on to have an incredible mothering experience. You won't want to trade it for ANYTHING (but you might not want to do it all over again, if that makes sense
s and best of luck. Be gentle with yourself, and allow yourself time to process this incredible change in your life. Acceptance and peace might not come easy, but it will come.
