Hi, I ve gone through your query and I understand quite well your concern Stomach pain and that kind of pressure that you are experiencing are usually caused by your expanding womb and hormones. It can sometimes feel like a stitch . You may also feel light period-like discomfort. These are quite normal and you have nothing to worry about. BUT, I should warn you to be careful and please call your doctor immediately If: 1. you experience severe cramps in your lower stomach/abdomen with bleeding that lasts for several hours (this could be a sign of a miscarriage) 2. you have severe constant pain in your lower abdomen/stomach, tenderness when you press your stomach and back pain with or without bleeding .(This could be a sign of placental abruption) 3. You have lower abdominal pain or dull back pain that comes with: pain or discomfort when urinating, need to urinate frequently, a raised temperature, foul smelling bloody urine because these are symptoms of an infection of the urinary tract. Wish you good health Dr. Ermira Biu
