For those who had back to back pregnancies did you go into labor earlier the second time around?

My son turns one tomorrow and I'm 34 weeks pregnant with our baby girl. Doctor said she's going to be another 9 pounder like our son. I went into labor early with him at 38 weeks and 4 days. My baby is already head down and I've had a lot of Braxton hicks. Think I'll go into labor early again?
