I am 21 weeks pregnant (5 months, 1 week) and I've been experiencing a lot of pain here and other, especially in my back and calves. I already have back issues, so pain in that area is normal, but lately it has been excruciating, and I just want to know if this is normal at this point in pregnancy? I ask this of mothers who have already been through pregnancy. This is my 1st child and I see my OB/GYN in two days. But, as I feel about a lot of doctors, the OB's I see are young and have no children, so they don't speak from experience, they speak from guessing, and I don't like guessing...especially when it comes to a child----and most of all, MINE! Your responses are greatly appreciated.
