To post to an individual you can PM them. I'm on the iPad application and it's done on that by clicking on their profile and clicking on send message (quick reply is a quick way to reply to the thread you are on).
Good luck with your appt today. I hope it goes well. If you need to chat let me know I'm just about to sign up for cycle 11 and I'm also struggling with knowing when enough is enough or when to look at other options. I'm just holding out for our miracle!
