In the next couple weeks your hips might start hurting, they are widening to help support your baby as he/she grows bigger. It can get a little painful so make sure you do a lot of stretches and it will help. You might also notice after that that the way you walk is different. I'm not talking about the waddle, that comes later, but once your hips widen your legs will 'sit' a bit differently and your feet might not touch the floor the same way they did before when walking. You might notice a change in your taste buds, things you like before you might not like now (for me that's chocolate, I used to be a chocoholic but now I can't stand it) and things you didn't like before you might like now.
there is constant changes to your body all through your pregnancy
It's hard to say every pregnancy is different..
