All those aches and pains are perfectly normal, just think about what is going on inside you, you uterus is stretching, all you other body parts have to shift and make way for your growing belly.
I was told basically that if you have any spotting associated with the pain then go and get it checked out, otherwise its probably just growing pains. If you do have any concerns, go and see your GP. They will be able to put your mind at ease!!

Good luck!!
