Normal pains?

I am 14 weeks along with my first baby and this is all new to me. About a week ago I started having some odd pains and I want to make sure they are all normal. None of them are so severe they do much more than make me start moving a little slower for a few seconds or just annoy me. First of all, my hips hurt like deep in the joints. If I sit or stand for any legnth of time without moving, when I start to move I feel like my hips are being pushed apart for just a few steps and then it subsides to a dull ache. Also, my rear end hurts. Deep inside, like near my pelvic bones and what not. It is strictly my butt and not in my lower back at all. This pain will hit me if I do a lot of moving up and down steps or an incline, sit still for a long peirod of time, or ride down a bumpy road in a vehicle. It is more annoying than anything else and does not slow me down at all. It is just this ache that will not go away. I mentioned it to my OB at my visit yesterday and they said as long as it does not stop me and the paid is not in my abdomen or my lower back I should not worry. However, lets face it, as a first time pregnant mom to be, I am going to worry. So....please just tell me this is all normal.
