Has this ever happened to anyone?

So I'm pregnant with my 4th child. It's a boy! I have three girls. But this pregnancy is the complete opposite than my others. I'm so tired of being pregnant because of all the pain 😩 they said my son is 95 percent bigger at this stage of pregnancy. I'm 32 weeks 1 day today. But at 30 weeks he measured to be about 4pounds and 5ounces. Now they are checking me tomorrow and then weekly. I'm just seeing if anyone has had this happen. I feel like my due date is wrong or something.
