Should I call Dr?

I'm 35 weeks well technically 36(Dr pushed me up a week cause of how low baby is and her measurements). I have been having horrible pelvic pain along with trouble breathing. I have been having back labor pain as well. However my contractions have mostly disappeared. This pain in my ribs isn't like when she was in my ribs it's different. I have a headache that comes and goes but when it is here it's so bad I can't even talk. Should I call the Dr? I don't want to be one of those people who constantly call about the smallest things.
