Hello! Thanks for putting your query in HCM. I am a Gastroenterologist(DM)
I think you are suffering from IBS
Few things to know about IBS:
1. Is a chronic diease which has relapsing and remitting course
2. It will never harm you even if it will persist for whole life
3. Stress, life events, and
anxiety leads to aggravation of symptoms
4. Intestine becomes hypersensitive so even discomfort is perceived as pain
5.Increase gas production leading to abdominal fullness and bloating
I hope this explaination must have cleared your doubts
I dont think you are pregnant as
pregnancy test was negative in March 2013
Take some prokinetic agent like
itopride,
proton pump inhibitor like
rabeprazole and some antispasmodic like mebaverine
