Trivial question - how come Ohbaby..

Lol I was looking up cloth nappies and stumbled upon this lovely site

I remember sex ed at highschool was pretty basic. we watched a video (must have been from the early-mid 90s), got told about STIs and learned how to put condoms on and about the other forms of contraception, but not a lot was really said about pregnancy apart from if you have unprotected sex it can happen.
Or maybe I just didnt pay much attention lol. My mum had already taught me ALL about sex ed well before the highschool classes. Only thing I really learned in them was about the STIs.
