Implantation cramping typically lasts from a few hours up to a few days, most commonly around one to two days. Some sources note that implantation cramps can last as long as a week, but usually, they resolve within a couple of days and are mild in intensity

. Key points about implantation cramping duration and characteristics:

• Implantation occurs about 6 to 12 days post-ovulation, and cramping usually coincides with this timeframe

• The cramps are generally mild, often described as light or dull aches similar to mild menstrual cramps

• Cramping may come and go in waves but does not typically become severe or disabling

• Implantation cramps tend to be shorter and less intense than menstrual cramps, often lasting only a day or two

• Some women may experience cramping for several days, possibly related to hormonal changes in early pregnancy rather than implantation itself

• If cramping is severe, persistent, or accompanied by other concerning symptoms, medical advice should be sought

In summary, implantation cramping usually lasts between a few hours and two days, occasionally up to a week, and is mild compared to period cramps
