Girls, I jinxed myself ? For the last three days my legs have been hurting, like to the bone ? and today my ankles have swollen a little. I thought it was from walking a lot for two days, but I've been resting for two days already — it must be because I'm 31 weeks along. What should I do so my legs don't swell even more?
