Hai mama! Early pregnancy can bring all sorts of aches, but numbness and stiffness like that, especially if it's affecting your movement, really needs a doctor's check, okay? Could be something simple or just how your body's changing, but better safe to get it looked at soon. A few of us mum friends had similar hand issues during pregnancy and it turned out different things for each, so you can't really tell without a proper check. Don't worry yourself too much, but do ring your gynae or clinic and get them to have a look, they'll put your mind at ease! Take care, yes?
