I had a constant pain in my right rib when I was pregnant with amber, the doc said that it was a pulled muscle, sometimes it hurt alot and other times it was just uncomfortable, as for the shooting pains in your legs, your baby may be pinching a nerve, causing the shooting pain, with both my pregnancies it was so sudden and so sharp at times it would floor me, one minute id be standing fine, the next my legs would buckle and id be on the ground haugh laughing and half crying....... Its normal and will go away after the bub is born
