bellies come in different shapes and sizes

I know that every pregnancy is different. Every woman carries differently. But I still can't help comparing my belly with other women. I'm 33 weeks and I look like my baby is full term and I'm ready to pop. My doctor said that my son is right on track with his growth which makes me feel better but knowing that I'm going to get even BIGGER is frightening! People ask me if I'm due any day and when I tell them I still have 2 months they are shocked. Is anyone else having a similar situation?
