I have been having that pain since around 30 weeks. And it's only getting worse. Unfortunately it is one of those things that happens in pregnancy as the baby gets bigger and puts more pressure in that area. . I used to see a chiropractor before I went on bedrest, and I thought it was wonderful and really helpful with a lot of the aches and pains in pregnancy. You will probably go soon, so hang in there! You are almost there now.
I have been having pubic bone and vaginal pain, and when it's bad the only thing I can do is rely on others. I just ask for help from DH or MIL/SIL...that was probably not the answer you are looking for! But at this time in my life I feel I can ask for a few favors. Good luck & hope you get some relief.
