Please tell me I’m not alone...

I’m currently 30 weeks pregnant and I’m experiencing horrible pain in my hips, tailbone and lower back. Every time I mention this to someone that’s already had a baby I always get the same response “I wonder why you are in so much pain...have you told your doctor?!” I can’t be the only pregnant woman that has experienced this type of pain. I’ve been experiencing pain since about 18 weeks, but now at 30 weeks it’s much worse. Has anyone else experienced severe hip, tailbone and back pain during pregnancy?!
