34 wks. 6 days lost plug and dilated

Holli
I went to the doctor today. She checked me since my Braxton hicks are pretty strong and I thought I'd lost part of my plug. Apparently I've love the whole thing and I'm 3 cm. This is my third baby. My first was born from start to finish in 3 hrs and was 2 days late. My last one was 2 weeks early and 16 hrs. I'm really freaking out now that I could go early. Has anyone else gone through anything similar? Doctor said she'll be happy to get me to 38 wells?
