your opinions please,pregnant ladys ☺️

So I'm clueless,If you protect yourself with pill,condom,and spermycid stuff..How many chance do you have to stay pregnant ?
Like,for quite some time I see so many young girls even from my high school,are getting pregnant..
I don't understand,are they beeing uncarefull or just want to have kids beeing so young?
Like pregnant girls all around me..
One is 16,two are 20/21,and 22-23...
So my question is,for you who got pregnant in age of like 16-20 did you wanted it to happend or you just weren't careful enough...?
Pardon my grammar,english is not my speaking language. ☺️☺️
