somewhere it should have been given to you at booking in, if not then ask your midwife or gp.
NCT classes are good if it's your first, people often end up with good baby-friends through there. I would probably go again if we had anyone to babysit DD while we were there.
Maths at my 2 appointments so far, my bp has been borderline high. The midwife just said they'd keep an eye on it, but I've been trying yonmake as many changes myself as I can to bring it down. Now on no added salt (I love my salt, so this is hard!) and trying to de-stress as much as possible. Having trouble with that one though.
12 weeks today, 1 more until next trimester! :)
