Contractions started

I'm 39+6 today. Contractions started last night, have gotten more regular and stronger throughout the day. About 45s each about 7 min apart now. I started loosing my plug two days ago, but I'm having bloody show at every potty break now.
I had a midwife appointment this morning and she said I was 1.5cm, 70% effaced, which doesn't sound like much, but I was zero last week, so that's something. She said it could continue and be tonight or tomorrow or stall and be next week. We'll see!!
