Labor 2nd Time Around?

Madison
Just wondering what your ladies' experiences were with your second labours/early labor signs?
I'm currently 36+5. Lost my mucus plug with bloody show on Friday the 3rd around midnight, so more like the 4th. 
I've been having contractions for weeks, but for the past couple of days they've felt a little more crampy/painful. 
I was dilated to a 1 on Friday, and the Dr today said she's starting to move down. 
I'm measuring 38 weeks. 
I feel really nauseous and unwell today (lots of loose BM, tmi sorry) and I'm super cranky. 
I've read that second babies don't engage until right before/during labor, so just wondering if she'll be here soon?
My BP is on the rise, and I'd like her to decide to come naturally before we have to worry about inducing. 
I'm still not quite term, yes, but I'm not too worried, as she's measuring ahead.
