I don't know if it's The baby or me but every time I eat or drink something it goes right threw me upsets my stomach so bad its done this before I got pregnant also idk what to do I usually take imodium but don't know if that is safe , I'm pretty sure its not healthy to pop imoduims everyday anyway but if I didn't I was in the bathroom all day
