question: Hi doctor, I am a 34 year old female who is generally in good health. Yesterday, I went to dinner, ate a lot, felt very full after and felt I had strong gas. But, I was not in pain, just felt very full. What freaked me out was this pulsating feeling on the left side of my stomach above my belly button. It continued throughout the day on and off. I woke up with a feeling of no appetite. I was bloated and burping a lot but not nauseous and there was no diarrhea. I have been on Avaine birth control for about a year now and have never missed a pill, but am concerned I could be pregnant as the burping was an earlier sign when I was. Other than the burping, I do not feel any pregnancy symptoms. Is this something that will just pass or should I be concerned?
