37 weeks swelling and weight gain ?

Cheyenne

i am 37 weeks pregnant tomorrow. So I was in the hospital the other day for kidney stones and my weight was 127. Today I went for my check up and my weight went from 126/127 to 135 in 2 days. Also my right ankle is so swollen it looks like it's broken. the Doctor just said the weight gain is from the IV fluids at the hospital and she didn't seem concerned about my ankle either. Am I the only one who thinks this is concerning?
