Good day! I am 27 years old and this is my third pregnancy. In the first two pregnancies, I gained about 30 kg each time. I couldn't control my appetite, and after 25 weeks, I had swelling. I felt like a balloon. After the last birth, it has been five years, I have almost returned to my pre-pregnancy weight. This time I am afraid of gaining as much weight again. A year ago, there were problems with my kidneys, and earlier, problems with my thyroid gland. Sometimes I get swelling, but it goes away in a few days. The question is, is it possible not to turn into a hippopotamus?
