Physical Therapy?

So I've been having severe pelvic pain to the point where I can't walk. I told my dr and she says this is normal but told me I should try physical therapy. They called me to set up an appointment and the soonest available is June 3rd. I'm due June 11th. Is this worth it? Have any of you ladies gone to do something like this before and if so, what does it consist of? Thanks in advance!
