I'm sorry that she showed up on you. That is the worst feeling of the month when you think you might have conceived, but then that witch shows her face.
It is no ones fault that there has been trouble ttc. Its nice that dh is as excited about the idea as you are. I'm sure dh will be right by your side to support you.
You should go out with dh tonight and have a date night and treat yourselves to something special to take your mind off things.
