Symptoms of Implantation Cramps
Cramps, experienced within several days after fertilization, will feel very similar to period pains. They are typically described as a heavy, dragging feeling in the pelvis and the lower abdomen. The discomfort is significant enough for you to take notice, but not severe enough for you to keel over in pain. In other words, although, you will experience nagging discomfort, it will not disrupt your day-to-day activities.
Sometimes the pain is more pronounced on one side of the abdomen. You may also feel the discomfort getting stronger at the end of the day or after standing for some time. Cramps may also first be noticed when any physical act increases the pressure on the abdominal muscles, such as sneezing, laughing or coughing.
