Hi I am 30 weeks and have been getting a sharp pain on my right side, just above my hip bone and to the side (kid've before my bump starts..IYKWIM).. It is not regular or anything, it happened about a week ago and again last night..

This morning I have terrible pain down low when walking (it feels lower then the front of the pubic bone) - does anyone have any thoughts ? could it be caused by consitpation ?!? Do you think it is worth calling my ob?
