Before drawing any conclusions regarding the presence of certain symptoms, we must find out everything about how real women feel in the 28th week:


I’m already 28 weeks old. I feel pretty good. Only one unpleasant moment still does not recede – my back hurts very badly, especially when I look a little like me. I have already gained 9 kg, but it seems to be normal.


I have already gained 9 kg. The doctor swears that this is too much, but I don’t eat much, everything is as usual. In the evenings, heartburn torments and pulls the stomach. My left leg is numb, as I sleep on my side. I can’t wait to lie down on my tummy!


Also at 28 weeks, but I’m still working, I’m very tired, I can’t sit normally, my back hurts, I get up – it also hurts, and I constantly want to eat, even in the middle of the night I get up and go to eat. I have already gained 13.5 kg, the doctor swears, but I can’t do anything. Can’t I go hungry ?!


I have 28 weeks. The weight began to rise sharply starting at Ձ 20 weeks. At the moment, the weight gain is already 6 kg. Too much, but I do not understand why so much, if I eat just a little, and there is no particular appetite. Doctors say there will be a big baby.


I only gained 6.5 kg. I thought it was even a little, but the doctor scolds me that a lot. Advised to do fasting days. I have only constant edema from unpleasant sensations, maybe a fasting day will be able to eliminate this problem at least for a while.


So we got to the 28th week! I added 12.5 kg, there is no edema, but heartburn often bothers me, sometimes the limbs go numb. Our puzzler has become a little calmer, kicks less and does somersaults. The belly is very large and has already managed to become covered with fluff, the nipples have darkened, the colostrum has become some kind of yellow!
