Large baby?

I'm a first time mum and 33 weeks. The past few days I've been feeling a lot of pressure and pain at the top of my ribs in the centre. 
Baby feels really big when he's moving about and I don't feel like I have much room left for him to grow! I can't imagine getting any bigger as I'm massive already. I'm worried that my baby is gona be huge 😔 
At 32 weeks my fundal height was 34cm. 
Did anybody else have a really big baby and have to be induced or have a c section? Or did you measure big and have a successful vaginal birth? 
I'm hoping I'm just worrying over nothing lol x
