Hi, I'm unsure as to whether I should be worried or not. I sometimes tend to over panic. Sorry for tmi. I started suffering from constipation around Christmas time (going once every 8days or so). Nothing in my diet changed or the amount of exercise I do. I have 3 young children but have always had my period regular ever after I had my twins (now toddlers) and youngest. However, last month I had a short period. Usually lasts 6-7days and quite heavy. This one seemed lighter and lasted 3-4days. This month I'm a week late. I thought I might be pregnant however test was negative. I'm unsure as to what could be happening. I have constant dull cramping but gets worse at night, back and leg pains on and off.
