Hi J. -
I may sound like a broken record since it seems that many of us are saying the same but I think it would be too early to tell if you're pregnant. Many of the symptoms you are describing are similar to the same symptoms that I have when I'm ovulating. Some months I have more cramping than others. The only thing that seemed a bit different was the sore breasts. Wait a few weeks and try a pregnancy test if you are hoping to conceive.
