When does implantation occur

Question

I've read different stories about this some say.. When you ovulate sperm will attach then meaning you've conceived and then an other site will say implantation occurs when your period should of been. So I don't know which one it is. X

Answer

The correct answer is neither. Sperm fertilize the egg within 24 hours of fertilization. During the next three days or so, the egg travels down the Fallopian tube before entering the uterus and implanting. It usually takes 6 - 10 days total. It typically happens on cycle day 20 - 24. It happens before (and causes) your missed period.

Answer

It occurs after ovulation, before missed period. But only about 30% of women have any bleeding. I didn't. Only cramps.
