7 months, and still no baby

My husband and i have been trying for 7 months. The past 4 days, ive been nauseous and having hot flashes in the morning (exactly the same morning sickness with my first, except i did gag with her). The 5th of jan is supposed to be my next period. And ive already started lightly spotting this ugly light brown fluid. So im praying that its just my fertilized egg implanting! Wish me luck. Im really starting to get down with all this trying and no results. If this is just my period starting, does anyone have any advice to help? Thanks, Leslie
