melonsrock, I'm the same - just coming up to 23 weeks, and the last couple of days have had puffy fingers and toes.
Not massive! No one else would notice except me, I shouldn't think. I'm a wee bit apprehensive though just because I suspected I might puff up - I tend to in hot weather anyway, but had hoped that might all come later on (I'm due July, this is my 1st).
I know my BP is fine, it's actually on the low side.
So far, I've has the following advice: - daily gentle exercise, like swimming or walking (which I do anyway) - tomato juice and celery, apple juice and celery if you have a juicer (though presumably actually eating said apple and celery wouldn't hurt either) - limit salty snacks. Also drink herbal teas, but I've never found one I like.
That's all totally anecdotal, and could be based as much in medieval witchcraft as science, for all I know (well - I understand there's good reason for doing exercise and avoiding too much salt). If anyone can offer any thoughts, I'd be grateful.
I sort of think that if I'm going to be a puffy person, that's just that and the luck of the draw etc, BUT I'd do anything sensible I can to limit it...
