@MissDaphne - I'm glad you shared your experience, because it's so easy to be frightened by spotting or bleeding during pregnancy and it's most often nothing to worry about. That's not to say you shouldn't call your doctor or even go to the ER, like you did - you absolutely should.
But while you're waiting, there's no need to panic. There's a good chance that everything will be fine. And stay off the Internet! It can be a terrifying place when you're pregnant.
