I'm not sure whats going on. Id say if you miss your period take a pregnancy test.
I would definitely take a pregnancy test if your period does not come and if it comes back negative, either wait a few more days or head into the doctor for a blood test. Also, it could be your hormones doing things to your body to prepare you for your period. I know when I got my periods, I would always have sore breasts.
Thank you :) boobs still killing me :( never have they been like this even before a period. Will wait and see if period comes. Doubt I am pregnant don't think it will ever happen for me :(
