My bestfriend caught her boyfriends little sister and her mates poking pinholes in their condoms which they keep in a draw beside their bed. She isn’t due for her period until next month. Is it lilkely that she could be pregnant?

yes, it is likely! i wouldn't keep condoms laying around like that, and use a backup next time. she can test with first response 5 days before her period.

Also, a trick my friend's husband does (to make sure they don't need to go get Plan B), after sex, they fill up the condom with water and look for leaks. Thankfully they've never had any problems, and this method has worked for them for years, and she's never had to take Plan B either. Its just a good thing to do in the future to make sure there isn't anything to worry about.
