Question: is it normal to throw up brown stuff while pregnant?
Answer: Fortunately, this so-called “morning sickness” (which can happen at any time of day) typically goes away by week 12 to 14. So you're used to the vomiting, but one morning you spot a red to brown tinge in your vomit — blood. While vomiting blood during pregnancy (or any time) isn't a good sign, it does happen.
