pelvic pain experience

I am currently approaching my 35 week. And yesterday on and off i have been experiencing terrible pelvic pain, also the pressure at the bottom. The pain lasted for 5mins. It was till last night the pain continously lasted for 50mins. I thought i was going into labour ? And my hub was so worried, he kept asking if im experiencing contraction. I totally got no idea what a contraction feels like. ??? When the pain finally subside, my hub told me : Can you please stop frightening me ? ???
