Maybe? Just don't get your hopes up too high without anything else accompanying it. I lost
a lot over a week ago (too early and freaked me out a little), but it had no blood. It hasn't happened again since then. My MW said it could have just been a time of heavier discharge for me. Ah...so lovely.

(A relief in my case, too, though) The only time I think I lost part of my actual plug was during my pg with my first DS. Thinking back, I was still pregnant for a good while after that...but...ya never know!
