Any else get really really sore boobs before period?

I could be pregnant, there's always that chance since I am sexually active.  But does anyone else get really sore/tender boobs each period? I've always had sore boobs as a symptom but here lately I've noticed they're getting incredibly sore. I've been pregnant twice (both ended, sadly) and the sore boobs I got with them almost match the sore boobs I get before a period. Is it normal to have such sore boobs before a period?
