TMI question about symptoms?

Rebecca
I am almost 10 weeks pregnant now, and I have had diarrhea every single day. Like drop what I'm doing and run for the bathroom, multiple times daily. My doctor won't see me until I'm 13 weeks. I was just wondering is this is a symptom of pregnancy? I do get nauseous a lot, and I have a lot of heartburn, but I haven't had an urge to vomit at all.
