Does having a big baby hurt as much?

So I went for a scan at 30 weeks and baby is measuring a week ahead, 4lbs 4oz! The technician said “he’s definitely not a small baby” I don’t know what I’ve done wrong, I haven’t been over eating or anything like that and I keep up with my fluids. But just because I could possibly be having a big baby, does that mean it’ll hurt as much? Will they have to preform a c section if he keeps getting bigger? I’m worried my pelvis might be too small or something(I’m 5’5). Please tell me your experiences for reassurance!

The lady asked me “what nationality is your partner if you don’t mind me asking” I told her he’s cook island, she said “that makes sense” we had a good laugh about it I wasn’t offended cause my son really does like his dad in the scan photos lol😂

Update: ALSO, she told me that baby is head down(thank god) but already low! Does that mean he’s gonna arrive early? 🥺🥺
