Fatigue, nausea, weight gain, look pregnant, stomach spasms, heat sensation in stomach, headaches neg hpts and blood tests. what else could it be?

Needs eval: Abdominal and pelvic symptoms are very vague and may be due to a variety of factors. First, I would suggest a pelvic ultrasound to rule out any problems with the uterus/ovaries. Next, consider a blood test for infections or thyroid issues. Persistent nausea could be a GI issue, or reflux. Stress can also be a factor. Due to the variety of symptoms, I would suggest physician visit for their help.
