Loss of a twin

Brittney
Went in today for my anatomy scan at 19wk2days and unfortunately found out we have lost baby B. Baby A is growing perfectly fine nothing wrong with her 💗 With me being this far along the doctor told me I would end up delivering the lost baby when I deliver baby A. Just curious if anyone else has gone through this and if there was any complications with the other baby? Dr said there was a risk of preterm labor with having baby b in there but it was higher up so I have less of a risk.
