I'm 22 weeks pregnant and I'm having none stop heartburn. The past couple mornings I've noticed blood in my vomit, should I be worried?

Yes. Call your ob. With the severe reflux, you may have erosive esophagitis. With the vomiting, you can develop a tear in the esophagus. Either way, you need to be checked so please get in touch with your doc or head to the er so they can do some testing to protect you and the baby.
