Hello, I am 14 months pregnant, I still have morning sickness, and the only food that really settles in my stomach is pretzels. Today when I woke up I was starving but I could only eat less than a handful before I started to feel nauseous. I also drank a half glass of milk because when I drink water in the morning, that usually comes back up too. After about a half an hour after eating what little food I did, I ended up throwing up stomach acid with pea-sized soft white chunks, and one very large chunk, about the size of a strawberry. This has never happened before. What caused this and what can I do to prevent it from happening again?
