What's going on

So about two days ago my legs ankles and feet started to swell really bad (to the point where I had to stay in bed all day) I thought maybe I ate too many salty foods but yesterday it got worse!!! I started my cycle today(only 1 day late) but it's really lite and I have little to no cramping (after having my daughter 14 months ago cramping has become really painful) should I be worried or do i need to give my period more time to fully get back on track?...oh and I'm having thick white discharge too
