Implantation occurs around six to 12 days after conception and, along with light bleeding, may cause cramps that last for one or two days, states WebMD. Implantation cramps are just one of the many types of cramping and pain that may occur throughout pregnancy.
If it's a blastocyst transfer, implantation could begin within 24 hours. If it's a day 3 transfer, it takes 2-3 days longer (but the same total number of days from fertilization). An embryo cannot start to implant until it has hatched. This occurs about 1 day after it forms a blastocyst.
