I had this happen in the last few days. Swollen feet one day replaced with swollen hands the next. In my view it's better to be safe than sorry so got my BP checked and did a urine test. All fine.

Pre-eclampsia is one of those things in pregnancy that you don't muck around with - always better to be safe than sorry. I worried for about 2 seconds about becoming a pregnant lady that jumped at shadows, then got over it. I'd rather get it checked than ignore it as 'it's just hot weather' than find out down the track something is wrong.
