Not yet…: You had sex 2 days ago on the 9th day of your cycle. Generally, it takes 3 days for implantation to occur after fertilization. Also, ovulation usually occurs about 14 days before menses so the timing would depend on how long a normal cycle is for a particular individual. Sperm can function for days and may still be around during ovulation.
