Pelvic Pressure

Ellie
I will be 30 weeks on Sunday and I am experiencing a great deal of pelvic pressure and tightness.  The pressure is right at my groin line.  There is no spotting or anything going on, just the pressure.  It's not Braxton Hicks- it's too low and lasts hours, not minutes.  Did anyone experience this?  Did anything help with the pain?
