Implantation cramps can typically be felt 6 to 12 days after ovulation, which corresponds to the time when a fertilized egg attaches to the uterine lining. These cramps are usually mild, described as light pulling, tingling, or pricking sensations, and tend to be brief and localized. Not everyone experiences implantation cramps, and their intensity is much less than menstrual cramps. This mild cramping can happen around the time when a period might be expected, making it easy to confuse the two, but implantation cramps usually occur before the missed period and last a shorter time, often one to two days. Tracking ovulation can help predict when these cramps might occur. In summary, implantation cramps can be felt as soon as 6 days post-ovulation, with most commonly occurring between 6 to 12 days after ovulation, and their sensation is subtle compared to period cramps.
