Why am I not able to have an orgasm...but never had this problem before?

I have never had a problem before, but for two weeks I haven't been able to climax. (no change in my relationship with my husband of 9 years) I get to that point but there is no release and my body just stays in that 'heightened state'. Last night it was followed by pain and difficulty breathing. We just moved and I don't have a doctor yet (although I've been searching for one since 5am). At first I thought maybe stress but...it's feeling a little more serious than that now. Any ideas???
