So confused....

Karina
Has anyone had spotting within the (6to12days) after ovulation (which I thought was implantation) along with cramping, nauseousness , super sensitive breasts, only to start your period when you were supposed to start?
I totally thought there was hope this month because of the spotting after ovulation...if it wasn't implantation... Then what was it? Should I be worried ? I stopped taking birth control at the end of October and everything was fine and all of a sudden this month I had those symptoms... Can anyone help?
