Kind of a stupid question haha

I'm a first time mom and I have a kind of stupid question haha. So, I'm 30 weeks pregnant and have gained 10lbs (which is good because I was plus size before and my OB only wants me to gain 15-20lbs total). I was 226lbs pre-pregnancy and I'm currently 236lbs. Baby is also measuring in the 80th percentile, so he's a big baby haha. So my question is, after baby is born, approximately how much of the weight will be gone? Because I know baby is part of the weight gain. I'm sure it totally varies person to person, so I'm more wondering what you all have to say based more on your own experiences.
