Hoping for two pink lines.

I have a 19mo old daughter and found out in December we were expecting our second child. Unfortunately I miscarried at 9weeks in January. Ever since then we have been trying again and have had no luck. It took us two years to get pregnant with the one we have no and I'm growing concerned that I'm going to have trouble again now. AF is due tomorrow. I was convinced I was pregnant because of all the symptoms I was having. Took a test this AM and sadly it was negative.
