I'm 29 weeks, I've piled on the weight in the last couple of weeks (admittedly helped by eating far too much crap) and I'm swelling up like a balloon by the evening, which didn't happen in my last pregnancy. My BP is absolutely fine (better than when I'm not pregnant!) but I have a small amount of ketones in my urine.
MW says as long as I feel fine in myself it's nothing to worry about.
So, nothing to worry about, right?
