Emmanue, I am sorry for your loss but you've come to the right place, I found a lot of support here.

In regards to the soreness of your breasts, I think it's completely normal to get that before your period is due, I always do. However, I really hope that you are pregnant now as breast soreness is also a sign of pregnancy, just wait few more days to do another test and let us know the results.

Good luck!
