It sounds like your plug BUT that isn't necessarily cause for concern. The plug can be lost and replenished, it doesn't necessarily mean labour is imminent. Are you still having semi regular BH's? Is there any pain to them? Or any other labour signs that are worrying you? If it were just the BH's and the plug, I'd we worried (hard not to!) but not alarmed. I would call my hospital and ask their advice, although often you'll get someone say to come in because it's easier that way and it goers the hospital. I know quite a few ladies who have lost bits of their plug throughout their pregnancy and have been fine
