Kind of freaking out over weight gain!

This was me pre-pregnancy. When I got pregnant I was already considered obese. My doctor told me I should only gain between 20 and 25 pounds.
I gained nothing the first 12 weeks and then by my 20 week appointment I had gained 7. My doctor told me that I was gaining on track and that I shouldn’t gain any more than 10-15 more pounds. I have not changed my eating habits since 20 weeks, and just weighed myself because we got a scale, and I’ve gained 13 pounds since my last appointment.
20 total.
That’s how much weight I was supposed to gain entirely! I am not sure why I gained so much weight so fast or what is going on, I’ve definitely had a stressful couple of weeks but I haven’t been eating anymore than I normally do. I guess I’m just wondering how much weight you’ve gained if you’re plus size like me? How much did your doctor say was normal? I’m really worried about GD.

This is me now, for reference. And my K fell off LOL. I had to Photoshop it in but didn’t save the photo shopped picture LOL.
