Hi, I'm 16 weeks preggies, yesterday I brought food from home and at lunch time I warmed them up, and they had funny , sour smell, and I ate two spoon cos I didnt trust the smell, in the evening I had a stomach ache, mild one and in the morning I rushed to the loo with a running stomach. At work now its painfull, I even went to the loo for the second time now, my stomach is runny, and when ny stomach start to irritate I had to run to the loo. My cousin says its a way of a body get s rid of unwanted stuff, is that correct, should I go to the doc now?Ps help
