There is always a possibility that you can get your period and still be pregnant. As for your bb's being sore, it could be that your period is due to start and that you are getting symptoms of this and the reason that you have never really noticed this before is that you are more aware of your body because you think that there is a chance that you could be pregnant and are therefore relating the symptoms together. I think the only way to know for sure is to test or go visit your doctor. good luck sweetie and take care
