(((HUGS)))) Sorry you are feeling sad ladytara. Praying he is a healthy little boy! I know you will love him so much.
To answer your question, I will guess and have a good idea I think, but we will not get confirmation of gender until the baby is born. My DH absolutely loves to be the one to tell me what we have once the baby is born. So I will give him this gift one last time! I am wavering as to if I feel it is a girl or a boy, but with all we have been through so far I know I will love this little one no matter what and that it is definitely our last.
