Hi, for the past 4 days i ve had diarrhea once a day only in the mornings when I have cereal with milk but for the rest of the day I feel bloated and crampy. I ve never been lactose intolerant so it s a little strange. I began to do some research and found that it could be a symptom of pregnancy. I ve been on birth control for a month and a half and take it correctly every day, within the hour. The day right after my period ended (the first day of the second month) i had unprotected sex and it s been a week since then with the diarrhea and bloating starting 3-4 days later. Can lactose intolerance start that fast if I am pregnant? Or could I have just become lactose intolerant?
