I am in big confusion with my health symptoms and cannot figure out what the problem or cause is all about? First of all, let me clear you on this that I have never been married or had sex. But, I feel I have pregnancy signs or symptoms like, gas,bloating,burping, breast getting bigger or heavier, stomach growing, gaining weight so rapidly yet eating nothing.....I feel very hungry and start burping or gas starts to build up. When I eat something spicy I feel burning in my lungs even thou I have raised on spicy food. I also have lower back pain which is terrible, after standing for a little long time, like washing dishes. I feel tired and exhausted. All these problems are they due to stress or what? The symptoms are so similar to be pregnant but I know I am not and because I never had sex so how can it be possible? I am also urinating alot nowadays. I was on zantac treatment for 2 weeks I started eating properly and everything was fine but I still did not have my second periods. It has been two months, I have not had periods at all. Please, answer me as soon as possible. I am very confused. why I am not having my regular periods? thank you!
