I Am Trying To Conceive A Baby. Iv Been Tracking

I am trying to conceive a baby. Iv been tracking my periods and ovulation. My main peak day should be today but 2 days ago and today I have experienced light pinkish color when I wipe. Iv been having cramps really bad and my smell is right on the dot. I have the signs of pregnancy. But my ovulation time is suppose to be right now. And implantation has already occurred? I have no idea. I am so lost to what is wrong with me.
