Cheers all. I'll chat to my GP if it starts really worrying me, but was just after some opinions and common sense. I don't eat ready meals and tend to stick to stuff that seems less messed-about(butter not marge,wholemeal not refined, sugar or honey not sweeteners etc) and thanks to lovely husband who's a dab hand in the kitchen the occasional pie and a reasonable quantity of cake alongside a mostly high fibre, low meat diet.

And gin not beer, which is probably less wonderful, and will of course stop before I start properly thinking about babies (I quite fancy doing some longer runs first; am still new to it all!)
