6w6d with twins - identical or fraternal?

My husband and I went for a early US this morning. We had a miscarriage last May so my nerves were a mess.

My nerves are a mess for other reasons now because we learned we are having TWINS! We already have a almost 2 year old!

I’m excited but nervous! I have a

small frame and I can’t imagine what carrying 2 babies is going to be like.

I just want them to be healthy in every way!

Anyone have some good experiences carrying and delivering twins?

Do you think my babies are identical

Or Fraternal? I can’t tell if there is one gestational sac or two?
