when is too early?

So I'm 32 weeks plus some days (3 or 4, I think). I've already started to lose my miscues plug though.. this is my 3rd successful pregnancy, so I've lost it previously, I just remember it being closer to the 37 week mark. It just seems a bit early. It's coming out in pieces, but it's coming out.. so I guess my question is, has anyone started to lose theirs yet? I know it typically means nothing.. but it does block the cervix and helps keep it from being infected. I see my doctor tomorrow, so of course I'll talk to her about it. I was just curious. Thanks ladies, gotta love the beauty of pregnancy!
