I did not have this for either of my other two pregnancies. During the last two weeks I have had this sharp pain that lasts only about 3-5 seconds. It strikes on only the right side of my lower back and runs all the way down my hip until the back of the middle of my thigh. It is super sharp. It literally has almost caused me to fall because it is so sudden, sharp, and almost debilitating. It is not long and tight like a contraction. Any other ladies experience this? If so, do you know what it is?
