Fat vs fluid

jenn6180

I started at a healthy weight and have gained 24 pounds at almost 33 weeks but I feel huge!  I feel like I'm wearing a fat suit.  My maternity pants are even starting to get tight and I think I'm gaining weight in my lower body not just my belly.  So I keep wondering, how can I tell what is real weight vs extra fluid.  My rings still fit but tight and my ankles are slightly swollen but not as swollen as a lot of people I've seen during pregnancy.
