Swelling, edema

My legs and hands have been swollen the whole day, I pressed on my ankles and there was a dent 😖 felt weird, anyways my blood pressure is normal I checked earlier today and it’s always been normal. I am very thirsty as well and my urine is so yellow like almost orange so I’m probably dehydrated but I can’t drink water it’s making me nauseous i feel like throwing up I don’t know why 🙁 I’m 37 weeks right now. Is the swelling concerning?
