How long does it take from conception to implantation?
Implantation IS conception. From fertilization (which is the sperm fusing with the egg) to conception (when the fertilized egg implants in the womb lining) takes about 6-7 days, so that would be 6-7 days after ovulation. It was probably a waste of time to do a test the day your period finished, your period would have told you that you were not pregnant.
