It depends on how long the sperm was on the shorts, because it would eventually die. Also, the menstrual cycle times, and how tight the shorts were, etc. So, it is indeed possible, but it is extremely improbable.
While there is nothing wrong or unusual about having sex during your period, if you are not using birth control you can't assume that you are safe from getting pregnant. Different women are fertile at different times in their menstrual cycle, and ejaculated sperm can stay viable in a woman's body for several days. This means that, yes, you may be unlucky enough get pregnant during your period. Use some form of birth control. Some women do use fertility awareness methods to learn about when they are ovulating, and plan sex this way, but it is neither easy nor foolproof.
