F.B.
It could be spotting from your period. I could be implantation of an embryo into the uterus, happens to LOTS of women. You won't be sure until your period is scheduled, but usually if it lasts more than a day, it's not pregnancy, to be sure take your prenatal vitamins (you should take these continually while you're trying to get pregnant as well as while pregnant) don't drink, etc. Good Luck...I'm waiting to see about this month too!!
