Hi girls! I've only recently found out I'm pregnant. The app calculated that I'm 4 weeks pregnant. I'm getting swollen ankles and feet every day. I wake up and my ankles are fine. But by 4pm, they're so thick! I'm not on my feet much at work. I sit a lot by my computer and walk around here and there. This week I've been wearing flat shoes with no straps but still have this problem. Is this normal at 4 weeks?
