Friend poking holes in Condom should I tell her bf?

So .....I was debating posting this but I need advice as she is my best friend since childhood . They’ve been together for 2 years and had a MC awhile back, he’s not ready for a baby but she is and she told me she’s trying to “trick him” into a pregnancy and she wants to start poking holes in their condoms. Will holes that small even cause pregnancy? Any other people heard of this before? Like WTF

-I’m at a loss of what to do right now. DH and I have been trying to conceive for 5 years, so her doing this makes me so upset. Should I tell her BF?

-Girls are crazy when it comes to babies!!!

Please no judging me here just asking what y’all would do!
