Girls, did you experience a sudden weight gain and swelling in your last trimester? I'm 8 months pregnant and gained weight normally, and in a month I gained 5 kg quite suddenly, but it doesn't seem noticeable, my belly is just bigger, and I have slight swelling in my hands in the mornings. Although I didn't have any swelling at all. Is this normal?
