Your question is incomplete because its important to know what your friends query was all about before these two cards can be deciphered in its proper context.
However as a generalised reply, I would say that:
Best Course of action (3 of Cups) would be to lighten up, be merry, look forward to the joy of having this baby.
Outcome with 9 of swords could mean: Too much anxiety and worries could be the cause of a self fulfilling prophecy. Anxiety could be about having a healthy baby etc. Maybe not truly ready yet to start a family perhaps so these to could be reasons for worries and fears.
Hopefully this interpretation may give you further insight for your reading.
