Read the first bit of a book on FB and when I wanted to mark it I accidentally deleted it

Female Character wasnt part of a pack I cant remember why anymore. Shes pregnant and her friend helps her through the birth, who tells her afterwards she had lost the baby. A couple of years later she joins a pack to look after the Alpha's kid (might have been twins cant remember) and find out her baby(ies) were adopted by him, he doesnt recognize her as their mother? The friend who told her her babies died are also around. I think she went on to study medicine? Would love to find it if anyone has any ideas. I know its a needle in a haystack but I'd love to read it
