Just about 30 weeks and gained 3 lbs in a week and a half!

Hey ladies! I’ve slowly gained weight through out my whole pregnancy, but this past week and a half I gained 3 lbs. I’ve gained about 18 lbs in total which I know is very normal. My question is are any of you ladies really packing on the lbs quick in the third tri? If I keep going at this rate I’m going to be a whale! Lol 😆🐳
