It's hard to walk???

I'm 32 weeks and for the last hour or more I've had a ton of pressure in my bottom stomach and I've had pain in my pelvis area, vaginal area, and inner thigh area. Which is making it harder to walk. It's like a hard tightening feeling and tingly that shoots down my leg. I called and left my doctor a message but I haven't heard back yet. Has anyone had this?? I don't know what's going on and it's freaking me out. Please help
