Second time moms, were your bumps bigger?

I am 30 weeks pregnant and my bump is the exact size it was at 40 weeks with my previous pregnancy! My fundal height is measuring 2 weeks behind and my weight gain is on track but my bump is MASSIVE! Anyone elses bump way bigger with the second? My son was 8lb 3oz and I was ended up with a third degree tear. I’m starting to worry this little guy will be much bigger 😫
