Delivering early

My son was born at 36 & 6, water broke naturally and was completely healthy when he arrived just a little jaundice. Do you think my second will come around the same time? I'm 34 & 3 today, I've lost multiple pieces of my plug, she's dropped drastically, and I've been having painful contractions that are regular but aren't getting closer together just yet. I'm hoping she will make it to where our son did or even farther, I just want to be prepared if she does come a bit early
