Gaining so much weight!

Jennifer
Hi guys. I am 19 weeks and 2 days today and I've gained 19lbs since my pregnancy started. I started at 200lbs .... every time I go to the doctor, I get the same speech about weight. I go to the gym 4 times a week, I eat minimal carbs like a cup of rice a day. I need to slow down this weight gain. And I don't feel like I'm eating more than before ☹️. Advice pls
