Implantation spottin: Some women will spot during implantation of embryo and thus mistake said spotting for a period. This is more common in those w/irregular or light spotting. If your question is whether you're pregnant or not, home pregnancy tests are most accurate when you're late, or 4 weeks after last period. Otherwise, unprotected sex around ovulation is best & most fun way to get pregnant.
