Muscle issues curing pregnancy?

I'm 9 weeks pregnant and I can't remember when arm started hurting but it's been a long time. It feels like I'm ripping or tearing my muscles it's a sharp pain.and then yesterday my hips have been feeling in a similar way. If i try leaning one way or the other I can feel a tendon or something rip or tear n it feels like I have a huge bruise there on my skin when you touch it. I'm wondering if I'm deficient in something? I'm taking prenatals. Or if this normal with hormones starting to work there magic? Anyone have any input?
