I hope this one is it!

I miscarried last October and ever since I've been trying to get pregnant again. At the moment I'm 9DOP and I've had some light cramping, no spotting, and I've been having a lot of dreams, and I've been waking up extremely early. I'm tired for most of the day and my mood swings have been crazy. When would be the best time for me to test? Oh and not to mention all I want ever is food. Keeping my fingers crossed.
