Hey mama! At 29 weeks, gaining 2 kilos per check-up is actually normal, that's roughly half a kilo a week which is what doctors expect sa third trimester, kaya don't stress yourself pa. A few of us moms gained around that rate and nag-deliver just fine, hindi kami nahirapan dahil sa weight; mas importante talaga ang how your OB monitors your overall health at baby's development. Regarding diet, I wouldn't restrict calories on your own kasi you and baby need the nutrition, pero maybe mention sa next check-up kung concerned ka, and ask if your weight gain is on track for your body specifically, because every pregnancy is different. Your doctor can give you peace of mind better than any of us here!
