Swelling and weight gain

Okay so I posted yesterday that I gained almost 5 lbs in one week. I’ll be 36 weeks tomorrow and I just noticed that my left ankle was slightly swollen. I had been working this morning and noticed it when I got home and was getting ready for a shower. Should I be worried ?
