Check PG test.: When an ovulating women has unprotected sex, there's a possibility of pregnancy or a sexually transmitted infection (if not in a long-term disease free mutually monogamous relationship). Any change in the pattern of your period may indicate pregnancy. Check a pg test. Follow the instructions & be sure kit is not expired. If negative repeat in a week. If negative see MD if next period's abnormal.
