Why do i weigh so much?

i'm 37 weeks pregnant.
before i was pregnant i have ALWAYS weighed 165 pounds. it's just how i'm built,
i lift weights and work out like a feen and it makes my body just ''stay'' at 165.
but i'm 37 weeks now, and i weigh 210 pounds!!! wtf
my legs are still the same, my arms seem a little fatter but i'm always insecure about my arms,
but in general besides, my stomach sticking out the way it should, i haven't gained any weight besides the baby.

like, my skin on my stomach is the same, there's not any like, rolls or flabs of fat or anything, so i can't figure out why i weigh so much.

maybe it is just the amniotic fluid?

could it be the baby that weighs alot? the doctor said it is hard to tell how much he weighs because of the position he is in (head down face up) meaning his back is inward, he is head first but he is facing upwards instead of in. so it's hard for the doctor to feel him out (his back)

idk i read that normally women gain 25 pounds, but that is no 25 that is almost 50!!
but no joke, my diet is still the same, and my legs arms back stomach, they all look the same, i don't see any added fat. it's just weird i guess lol

i mean, i don't CARE, i think it's funny i tell everyone, yeah i weigh 210 pounds guys. they don't even believe me because i'm 5'4 they just all laugh like i'm joking but they don't realize that i REALLY do weigh 210 pounds lol so idfk man it's weird.
