How Long Does Implantation Pain Last?

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.

Both bleeding and cramping can occur throughout the first semester of pregnancy but are only slight compared to menstrual bleeding and cramps, reports WebMD. Any more significant cramping or bleeding may be an indicator of a problem, such as ectopic pregnancy or miscarriage, according to WebMD. Women who are concerned about the length of time that they have been experiencing cramps or who have been experiencing severe cramps are advised to see their doctor to rule out potential complications with their pregnancy.
