Swollen ankles on one side??


So I’m 36 weeks 5 days and today when I got home I noticed my ankles were swollen. I will say my water intake was way lower today than it’s ever been and since being home it’s definitely went down but it’s still not gone? I’m wondering if I should be worried? I haven’t had any rapid weight gain, headaches, blurry vision or anything and baby is still moving. I really don’t wanna rush to the ER for just edema if that’s what it is. Any advice. Picture below!
