Is my baby going to be big or is this normal?


I'm 20+6 and just had my OB appointment this morning. She said that my belly is measuring for 22 weeks. My SO was almost 9 lbs at birth, I was a preemie because of being a twin and my mom had pre-eclampsia so I don't know how big I wouldn't gotten if gone to term.

Is this normal to measure bigger or does this mean that I'm going to have a big baby? (he's also a boy)
