Possible: Pregnancy occurs near ovulation=release of egg -- about 14 days AFTER your period starts. Sex 2 days before your period starts is RARE to cause pregnancy but possible (but very high for sexually transmitted diseases). No symptoms of pregnancy show at this time until usually 4-8 weeks later. Your sore breasts are from your period starting. PLEASE use condoms to prevent STDs and pregnancy! :)

Periods: No. If you had a period, or if you are on your period you are not pregnant. If your period has not come yet, then you should test the morning after the first missed day.
