here is what's happening with me. I had an on time and normal period that ended ~ 11 days ago, then, 4 days later my breasts became very painful/tender as they do during PMS. It is still going on (8 days now). I'm not sure what to think about it. I had my hormone levels checked in December and they were normal. I guess my question is do you think that I may be pregnant? What else could this be?
