“I have a friend who isn’t on any birth control. She and her boyfriend have recently been having a lot of unprotected sex. She recently has been having a lot of trouble eating things such as bread and milk because they give her an upset stomach. Can an early pregnancy cause symptoms like that?“
Early pregnancy can indeed cause a change in women’s diet. Some women find foods intolerable, may crave other foods, or may experience nausea/vomiting. Encourage your friend to see her health care provider. If she is pregnant, she will need to start her prenatal care. If she is not pregnant, then she can begin to explore other health concerns associated with her intolerance for certain foods.
