Hun - get it checked out. It could be nothing, or signs of early pre-eclampsia (as I am sure you already know). I have had SEVERE oedema for the last couple of weeks, I mean, even my knees and upper legs are swollen. Only have just now been diagnosed with mild pre-e as BP is up and showing some protein in wees.

Just keep your eye on it and note any sudden changes.

Good luck!

PS my right foot and ankle is about 20% more swollen than my left, I think this is fairly normal.
