I am a 50 year old healthy female who is experiencing cramping that comes and goes in lowest part of abdomen( throughout the month, not just periods). I also get a moderate pain that lasts a couple of days and then subsides that is located 6" below belly button and about 4" to the right. I am currently experiencing menepose symptoms and am taking a low dose birth control pill. These symptoms of lower cramping have been going on several months but the pain on the right side started about a week ago. I am also experiencing constipation that is mild. My periods vary from heavy to light and are becoming more painful with no preference to being heavy or light.
