Suggest Treatment For Stomach Pain,bloating And Nausea

Hi, for the past 3 weeks I have been getting a few worrying symptoms. I have been feeling bloated, have on and off nausea, hungry all the time, weak and exhausted that I m finding it hard to stay awake at work. I also feel light headed and faint. Last weekend I started my period but it only lasted 2 days and was lighter than usual (I m always very heavy and usually lasts for 7 days) I ve done a few pregnancy tests but they have all been negative. I had a miscarriage 3 months ago and I have coeliac disease. I am on medication for vit d supplements and 5mg folic acid. I have also been getting lower stomach cramps, very mild, and I can t lay on my front at night because it hurts my stomach... Any help? Leanne
