swelling ankles

Ja

is it normal for my ankles to start to swell? im 21 weeks been getting my mekena shot since 19 weeks. and today i woke up noticed my ankles were a little swollen. it's now the end of the day and they even more swollen! My calf hurt to my left leg too. I go back Thursday for another dose and will speak to my RN about it. I just don't know if is something for immediate attention. never had this with my other pregnancies. Any one can relate?
