I think any color other than white should be checked out just to make sure. Is there a bad odor to it?
I too am 17 weeks and I havent experienced this yet. Im a 1st time mommy so I dont have to much to say. Maybe someone else has better advice?
Can you call your doc office and talk to one of the nurses there? They can tell you if you need to be seen or not. Plus there usually is another doc you can see in the event that your doc is gone, like his collegue or something.
Im like you though, I need to know....lol
