Condom please help

Sophia

So my bf and I plan on having sex for the first time really soon and I won’t be taking the pill as I’m not telling my mum and I have no other way to get it, he will wear a condom and he says he will pull out when he cums but I’m so so scared about getting pregnant if there is a hole or the condom splits or anything, I’m so worried, does anyone have any advice?
