I had dry sex both of us wearing 2 layers of clothing. Now I'm experiencing heavier, sore breasts, cramps, and my period is a few days late. Pregnant?

Dry sex. Dry sex should not lead to pregnancy. The 2 layers of clothing each of your wore, acts as a barrier to the movement of the sperm. If you have engaged in other sexual activity then pregnancy might be possible.
Do pregnancy test. If you had clothes on and no penetration and exchange of semen to your vagina, than it is unlikely that you are pregnant but you do have symptoms of pregnancy, missed period, heavier and sore breasts so do a pregnancy test if negative and still no period repeat the test in couple of days to make sure you are not pregnant.
