Could this be an ectopic pregnancy, although I have had changes such as weight gain, fatigue, or increase milk? back pain, headaches, dizziness, no period in five months, pain in the left lower quadrant abdominal pain, shoulder pain.
If you have not had a period in five months an ectopic pregnancy would have been diagnosed earlier. It seems that different processes are going on. Your symptoms are typical of an infection of the urinary tract is not yet controlled , or ovarian cysts, or thyroid hormone. You should see your doctor for a checkup.
