Swollen ankles and feet in afternoon!

Asia

So I’ll be 31 weeks tomorrow and I have noticed that I now have cankles😩😂😭is that normal ?! No I never have high blood pressure when I go to the doctor and nothing else is swollen(face or hands) . I do have gestational diabetes though( was just diagnosed last week and have been keeping my numbers under 120 since then YAY ME) . But I’m worried about preeclampsia !
