Weight Gain Help

Please help me! I am 25+4 and I cannot control my weight gain! I was 130 pre-pregnancy and 5’4. I never had any trouble with weight before. I could eat whatever I wanted and my body consistently stayed at 130. I am a FTM and I cannot keep my weight under control during this pregnancy! I am weighing 162 now! That’s 32 lbs and I still have three months to go! I exercise everyday by working outside or taking my dogs on a walk. I am eating much healthier and not over indulging during meals. I don’t know what to do. I don’t know how to control it. I’m so devastated because I’m already up this much and I still have three months left. I attached pictures so you can see I was pretty small prey-pregnancy. My wedding dress was a size 2. And now I can barely fit into Large panties. My legs are swelling like crazy.
