I am a 28 years old married female. From some time I have been witnessing a dull ache in the lower part of my abdominal. I have noticed that pain into the stomach varies from slight to strong. I wish to know what is the cause of pain? Is it normal menstural pain or something else? I have heard about Implantation Cramps that happens to women at the time of ovulation. What is the real cause of this pain and what meausres to be taken to cure it? Also say me some symptoms of implantation cramps.
