Now I'm 27 weeks pregnant, but I'm having a bigger belly like 39 weeks...is there any problem?

I had a huge belly but I was carrying a singleton. Public will look at me as if I was carrying multiple. Only to find out that I had a pregnancy condition called Polyhydramnios which is high volume of amniotic fluid. But my baby weighs normal though. Although seldom but yes, I also do have times of breathlessness but it's normal when you're pregnant as all of your organs are pressed by your baby hence the difficulties to breathe. Do check with your gynae for any concern cos every pregnancy is different and yours may probably be normal, just a huge belly that's all.

check with your doctor
