I had sore breasts from nearly the moment I became pregnant... it was always my first sign. Everyone is different though and it could be caused from ovulation. I would wait until at least 2-3 days before you expect your period to test and if you can hold off I'd wait until you are truly late as those tests get expensive and when you're hoping for a baby you can easily consume yourself with thoughts of "maybe I tested to early", "maybe it's wrong" and before you know it you've spent a ton of dough on HPT's. Good luck!
