What could these symptoms mean?
19 year old female. For the past two weeks I've been burping excessively. I have been avoiding soda and the use of straws to see if that helps. I am also experiencing nausea (no vomiting) and heartburn all hours of the day, which I have been trying to subdue with Tums. I stopped taking my birth control fairly recently and my last period, the first once since I stopped taking the pill, was one day late. But this month, it is three days late so far. Suspecting I might be pregnant, I took a test two days ago. It was negative. What could be the reason for these symptoms? The soonest I can see my doctor is 10 days from now!
