Rainbow Baby/FTM Labor *Possible Trigger Warning*

I’m currently 33wks with my rainbow baby. I had 3 mc’s, 2 natural and one with medication (had to have D&C because everything didn’t pass) all around 8 weeks. This will be my first baby. I was wondering since I’ve had a history of miscarriages, will labor go fast with this baby or will I still have that “ftm labor” where I’m in labor for days? I ask because a lot of people experienced shorter labors with their 2nd, 3rd, etc baby. How long was your labor with your first if your first is a rainbow baby?
