I have lost a son and for us the most wonderful thing was the meals that were delivered. Frozen meals, meals at dinner time (wonderful women showing up on our doorstep with dinner!) and help with housework.

Ask your friend if she feels comfortable with you atm, tell her you will understand if she doesn't and that you really want her to be honest with you. If she says she's fine with you being pregnant all is well and good, if she isn't then maybe your husband or a mutual friend could take them a meal from you.
