Will the doctors tell me how much my baby weighs?

I’ll be 27 weeks and 5 days at my next appt and i’m wondering if my doctors will know how much the baby weighs and if they will tell me? They have never told me her weight before or anything although they measure my belly at every appt. Not sure if thats how they know the weight or not but i’d like to know how much she weighs now. Do I just ask?
