large baby?

had a check up with the midwife today. everything is great. but she says I'm measuring 2-3 weeks ahead of what I'm "suppose" to be. I've been getting aload of aches and stitch like pains mainly on my right side under my bump when I'm walking which is normal specially for my third baby. I am kind of worried though baby will be big because both my boys were 8lb 12oz so any more then that scares me 😂

current position of baby lol probs explains why I'm uncomfortable.
