I look like I am 6 months pregnant, I'm nauseous, really tired, lower back pain, heartburn, pelvic pains and groin. Pains down my legs and arms, like a trapped nerve pain. I'm constantly burping, which I never do! I have been feeling like this for a month now and have an appointment with my GP on Tuesday but I'm worried I'm going to sound stupid and she will just brush it off because of my age and no history. Am I being ridiculous? Could it be something else?
