If you drink a lot of hawthorn infused water for a long time, it can excite the smooth muscle of the uterus and cause uterine contraction, especially in early pregnancy, which may lead to abdominal pain, bleeding and other symptoms of miscarriage. And hawthorn infused water is too acidic, some pregnant women may produce excessive stomach acid, heartburn and acid reflux symptoms, affecting appetite and digestive and absorption functions. A healthy, balanced and varied diet during pregnancy should include fresh vegetables and seasonal fruits, an increase in fluid protein such as lean meat, eggs and milk every day, and proper activity so as to facilitate the healthy development of the fetus during pregnancy.
