I live in the UK, but I was born in a Scandinavian country and lived there until I was 22. There you have free access to BC until you are 25 after that you have to pay for it.

In the UK, BC is FREE FOR EVERYONE. If you want fancier Durex condoms, yes you have to buy them. But BC for women is free. Still, there are so many teen pregnancies here. I cannot tell you why that is. Perhaps the sex education still isn't very good, perhaps allowances actually make it a financially viable option for women to have children than work in a minimum wage job. I don't know. But evidently, people who wants to have children will have them regardless even if you throw BC in their faces.
