I’ve gained so much already!

I need help! I gained 30 lbs so far. That’s how much I had gained altogether during my last pregnancy! I’m about 30 weeks. I have 10’weeks to go! This is not good. I was already overweight to begin with. I was about 168 and I’m 5’4. I feel I’m losing control. I had my son a year ago, so I have a lot of pubic pain so exercising has been hard. Any tips on how to control these cravings and hunger? 😭😭😭
