You cannot become pregnant when you have pants on.

You cannot become pregnant when you have pants or other kinds of clothing on that covers your genitals⁠ (genitals: Body parts that are generally, culturally, scientifically or personally considered to be external sexual or reproductive organs.) .

No, seriously, listen up:
 

YOU

CANNOT

BECOME

PREGNANT

WHEN

YOU

HAVE

PANTS

ON.

No, not even JUST you but no one else, because you think you are some kind of one-in-a-million-something-or-other: Nobody is that special, not even you. (Which is not to say you are not special: I am sure you are.  Just not THAT special.)

Not even unicorns. Or magicians. Or flying pigs. Nobody.

There IS no one-in-a-million-with this.  Only a none.

Last time: Were you wearing pants during anything you are worried may have caused pregnancy⁠ (pregnancy: The state of carrying a developing embryo or fetus within the uterus. Medically, someone is considered to be pregnant when an egg has been fertilized by sperm, cells divide, and the fertilized egg is implanted within the lining of the uterus.) ?
 

YOU DO NOT NEED TO BECAUSE THAT CANNOT HAPPEN WHEN YOU ARE WEARING PANTS.

IT JUST CAN’T.
