Are you thinking you could have conceived 9 days ago when your DH came home? If so, it may be too early to get a positive hpt. Your cervix is usually high and soft when you are fertile, around the time you ovulate. It goes back down and gets firmer after you ovulate. Not knowing your cycle, I couldn't really say what is happening. You may want to wait a couple days and test again. HPT's are more accurate around 14 days past ovulation. Good luck!
I'm sorry for your loss. The same thing happened to me.
