Mucus plug. Due date tomorrow!

Vanity • Married mother of 3.

I’m now 39w6 days. Yesterday I went into see my doctor. She checked me told me I was 2cm dilated, 50% effaced and that my cervix is really soft and looks really good! She swept my membrane per my request. (This is my 3rd baby but I have so many years between my last that i don’t remember everything!) my cervix is still really high but she said it wasn’t a problem at all. After the sweep she told me hopefully I go into labor naturally (which is what I want) she told us to have lots of sex and walk. So we have. Today I was cleaning up our place I stop to use the bathroom I lost my mucus plug and I had my blood show at the same time. Does that mean I’m going to go into labor soon? Or can it still take days?! Anyone else have this happen??
