No chances at all: If you are 18 years old and is a virgin, your hymen should be intact, unless and until an accidental rupture of hymen happened and not due to sexual intercourse. Anal sex do not lead to entry of sperm through vagina. Then u having a period, makes it highly unlikely for u to be pregnant. Pregnancy is one of the most common causes of missing your period in your age and u did have your period.

Yes: Theoretically, but not practically. If semen leaked onto your labia and into the vagina, unless you had an imperforate hymen (no opening in it) it would be possible for you to become pregnant, but a rate occurrence. If you got your period afterwards this makes it even more unlikely.
