I think I lost my mucous plug

[ringstrue]

no it means nothing. Wait to you have signs of labor like bloody show, contractions, or water breaking.

I'd mention it at the appt but not call. You can sometimes lose part of it too. And just because you lose it doesn't mean you will start labor right away.

I lost mine 1-2 weeks before I went into labor. I didn't call the doctor or anything. It happened when I was at work and was kind of shocking!

Agree with pp's.

The lady who taught our childbirth class once had a woman fish her mucus plug out of the toilet to bring to her so she could see it. She said that was completely unnecessary. Lolol So my only advice is not to do that.
