I have a friend doing her last round of IUI. She said she got the smiley face and to send good thoughts for her that this round works out. Does that mean she will know in about 2 weeks whether it worked? Should I follow up and ask how she is doing or rely on her to share any good news when the time comes? I don't want to ask for an update if the news is bad, but don't want to seem uncaring, since she specifically asked for positive thoughts!

Yes, I know I am completely clueless about this, which is why I am asking, so please forgive my ignorance!
